Frequently Asked Questions

I HAVE USED THE CONTACT FORM ON YOUR SITE BUT I HAVEN’T RECEIVED AN ANSWER FROM THE SUPPORT CENTER! HOW LONG SHOULD I WAIT FOR SUPPORT?

Our support team will contact you within 24 hours after receiving your message. The response time is usually between a few minutes and several hours depending upon the team’s workload. If after 24 hours you still haven’t received a reply, then please resend your query and please ensure that your e-mail address is correctly written.

I AM A REGISTERED USER OF REVO UNINSTALLER PRO 3.X/4.X, AND JUST BOUGHT AN UPGRADE TO VERSION 5. SHOULD I UNINSTALL THE OLD VERSION FIRST BEFORE INSTALLING THE NEW ONE?

We do not recommend that you uninstall version 3/4 before installing the new version 5 because you will lose both your current settings and other user data. The best approach is to install the new version, as it will simply overwrite the current one, and you will then keep your data and settings, just as happens with minor updates.

WHAT IS THE DIFFERENCE BETWEEN REVO UNINSTALLER PRO SETUP VERSION AND REVO UNINSTALLER PRO PORTABLE?

The main differences between the two versions of Revo Uninstaller Pro are the licensing type and the portability of the Portable version. The standard (installable) version has a license that is per computer. This means that a license is purchased for a specific number of computers, but anyone who uses them can also use Revo Uninstaller Pro. The portable version has a license per user. This means that only one user is allowed to use Revo Uninstaller Pro, but can do so on an unlimited number of computers (just not simultaneously). The portable version is designed to be run directly from an external USB device (like a thumb drive), without leaving any traces on the computer’s hard drive or Registry, on which it is run. This allows you to always have a copy of the program with you.

I HAVE REVO UNINSTALLER FREEWARE INSTALLED, AND I BOUGHT THE PRO VERSION. SHOULD I UNINSTALL THE FREEWARE VERSION BEFORE INSTALLING THE PRO?

Both versions of Revo Uninstaller – Freeware and Pro – are installed in different folders, and are totally independent of each other. They do not share common components or modules and so it is not a problem if you have installed the Pro version while the Freeware is still on your system. However, the Pro version is vastly superior and so you should not need the Freeware version anymore.

WHY “PIN TO” IS MISSING ON REVO UNINSTALLER PRO’S SHORTCUT AND IT CANNOT BE PINNED TO WINDOWS 7 TASKBAR OR START MENU?

This is because Windows 7 does not allow pinning programs containing the word “install” in their name. You can overcome this problem by creating a shortcut on your Desktop of Revo Uninstaller, and rename it to just “Revo”, or anything else that does not contain “install” as a word or part of a word.

IS REVO UNINSTALLER PRO COMPATIBLE WITH 64-BIT VERSIONS OF WINDOWS?

Yes, Revo Uninstaller Pro is fully compatible, and natively supports all 64-bit versions of Windows, starting with Windows Vista and up to the latest Windows 11.

WHY SHOULD I USE REVO UNINSTALLER PRO WHEN I HAVE A REGISTRY CLEANER, AND IT FIXES ALL ERRORS IN MY WINDOWS REGISTRY?

There are tens of thousands of applications that leave a lot of unused data, such as registry entries, files, and folders in your computer. Not all registry keys left in your computer are errors, and third-party registry cleaners cannot therefore detect them. Leftover registry keys in combination with leftover files make a registry cleaners’ job impossible to fulfill, but Revo Uninstaller Pro helps you remove the leftover registry keys, files, and folders after uninstalling an application.

HOW CAN I CLOSE(EXIT) OR MOVE THE HUNTER MODE WINDOW?

To close the small blue target window, which appears in the upper right corner of the screen when you are in “Hunter Mode”, just rightclick and then choose Exit, or Open Main Window.

To move the blue target window, click and hold it with the middle (scroll) mouse button and then you can drag it to the desired position on your screen.

REVO UNINSTALLER PRO’S WINDOW SUDDENLY DISAPPEARED, AND WHEN I TRY TO LAUNCH IT AGAIN, I SEE AN ERROR THAT IT IS ALREADY RUNNING.

Most likely you have enabled Hunter Mode. Look for a transparent floating target icon on your Desktop or a Revo Uninstaller Pro icon in the system tray, right click either one, and select Open Main Window. If you do not see the aforementioned icons, check the Task Manager (Ctrl+Shift+Esc on your keyboard) for Revo Uninstaller’s process, and close it. Then try launching Revo Uninstaller again.

I DOUBLE CLICKED ON REVO UNINSTALLER PRO’S SHORTCUT BUT NOTHING HAPPENS. REVO UNINSTALLER PRO DOES NOT START.

You can try to start Revo Uninstaller Pro from your Start Menu, if a shortcut is also available there. You can also try to start the executable (RevoUninPro.exe) directly from its folder: C:\Program Files\VS Revo Group\Revo Uninstaller Pro.

If both of the above fail, it is possible that a security program (antivirus/antimalware) is interfering. Please add Revo Uninstaller Pro’s folder and processes to the exclusion lists of your security software, and try launching Revo Uninstaller Pro again.

I TRIED USING THE AUTOUPDATE FEATURE IN REVO UNINSTALLER PRO BUT NO CONNECTION COULD BE ESTABLISHED TO WWW.REVOUNINSTALLER.COM.

Open the Windows Control Panel, go to Internet Options, and then the Advanced tab. Make sure the following two options are disabled:

  • Warn if changing between secure and not secure mode
  • Do not save encrypted pages to disk

REVO UNINSTALLER SUDDENLY CLOSES OR STOPS WORKING WITH AN ERROR MESSAGE.

If this is a reoccurring issue, a more in-depth investigation may be required. Please contact us with detailed explanation and a step-by-step description how to reproduce the issue.

CAN I TRANSFER MY LICENSE FOR REVO UNINSTALLER PRO FROM ONE COMPUTER TO ANOTHER?

Yes if you are a going to change your computer with a new one, Revo Uninstaller Pro version 4 offers the option to deactivate one’s license. To do so, click the Menu button (in the upper right corner), select “Deactivate License” and confirm by clicking “Deactivate”. You can now activate using the same serial number on the new computer.

Renewing your subscription will be necessary if you wish to be able to update to newer versions. You can download a specific version at any time from the release history page of Revo Uninstaller Pro — here, simply click the version number to download the desired version.

However, renewing your subscription is essential if you wish to update to newer versions.

IS THE LICENSE OF REVO UNINSTALLER PRO A LIFETIME LICENSE?

Purchasing a License for Revo Uninstaller Pro 4 or above includes free technical support and free updates while your update subscription is valid (not expired). The previous question and answer explain your options once your license has expired.

But remember, you can continue using your existing activated version, for which you have purchased a license, for as long as you want.

Dependent upon features in new versions, you can decide to renew your update subscription by purchasing an updated license (significant discounts will be applied).

I BOUGHT A LICENSE FOR REVO UNINSTALLER PRO FOR ONE COMPUTER. ON HOW MANY COMPUTERS CAN I ACTIVATE THE PROGRAM?

Licensing of Revo Uninstaller Pro is per computer, so buying a license for one computer allows you to register the program on only one computer. If you want to buy a license for 3 or more computers, or if you are already our customer, you will be able to buy additional licenses at a discount. You could also consider the alternative and buy a license for Revo Uninstaller Pro Portable version. See the question and answers in the General Section FAQ’s above.

WHAT KIND OF LICENSE FOR REVO UNINSTALLER PRO DO I NEED IF I HAVE INSTALLED MORE THAN ONE COPIES OF WINDOWS VERSIONS ON MY COMPUTER (DUAL/MULTI BOOT)?

I CANNOT ACTIVATE ONLINE BECAUSE THE ACTIVATE ONLINE BUTTON IS GRAY. WHAT DO I DO?

First, please make sure that you have entered a user name. It can be whatever you wish, but the field is mandatory.

If you have entered a user name, please make sure that you have entered your serial number exactly as you have received it.

DURING THE REGISTRATION PROCESS, I SAW A MESSAGE “REGISTRATION FAILED”. HOW DO I PROCEED?

Please click ‘Retry’, wait 10-15 seconds, then click the button again. Repeat this a few times, and the registration should be successful. If the issue persists, please contact us for further assistance.

WILL I BE CHARGED AUTOMATICALLY WHEN MY SUBSCRIPTION EXPIRES?

By default, the Annual Update subscription option is deactivated. It must be explicitly enabled by you, the customer, during purchase. You can check if it is enabled in the confirmation e-mail, containing your license details.

If you have activated the Annual Update Subscription option, you will receive a reminder 14 days prior to the automatic charge for the updated subscription license.

HOW DO I UPDATE/EXTEND MY SUBSCRIPTION PERIOD?

Open your activated Revo Uninstaller Pro, navigate to the Main button -> Update subscription, and enter your newly provided serial number to extend your subscription.

CAN I EXTEND MY SUBSCRIPTION BEFORE THE EXPIRATION DATE?

Yes, you can extend your subscription at any time. After the new purchase is completed you should use the Update subscription option. This will allow you to extend your current subscription by entering the new serial number that you have received.

HOW CAN I CHECK WHEN MY SUBSCRIPTION EXPIRES?

Open Revo Uninstaller Pro, and click the Menu button -> About. The About window will display both the expiration date and the remaining days of your active subscription.

WHY HAVE I BEEN CHARGED FOR RENEWAL YET REVO UNINSTALLER PRO SHOWS THAT MY SUBSCRIPTION HAS EXPIRED?

A new serial number was generated and sent to you after the renewal was completed. You will have to use the Update Subscription option in Revo Uninstaller Pro with your new serial number in order to renew your subscription.

IS THERE A DIFFERENCE BETWEEN A “NEW” LICENSE AND A “RENEWAL” LICENSE?

The only difference is the intended usage of a license. Any newly purchased license can be used to either activate on a new/additional computer, or to update/extend the subscription period of a previously activated copy of Revo Uninstaller Pro 5.

Please note that the subscription period of a license starts at the moment of purchase, not when first used.

CAN I RENEW FOR FEWER OR MORE DEVICES THAN MY PREVIOUS/CURRENT LICENSE?

Yes. Since all licenses are completely independent of each other, you can purchase a new license (renewal) for as many computers as you want. Previous purchases do not limit new purchases in terms of type of license, quantity, or subscription period.

HOW DO I UNINSTALL PROGRAMS WITH REVO UNINSTALLER PRO?

Before uninstalling a program, make sure that it is not running. Check the system tray (in the Taskbar near the clock) for any icons belonging to the program you want to uninstall. If there, try right clicking them, and look for an option like “Exit”, “Quit” or something similar. Then start the most popular Uninstall procedure as described here.

HOW DO I UNINSTALL A TRACED PROGRAM WITH REVO UNINSTALLER PRO?

I AM TRACING AN INSTALLATION OF A PROGRAM WITH REVO UNINSTALLER PRO, BUT THE PROGRAM’S INSTALLER ASKS ME TO RESTART THE COMPUTER. HOW SHOULD I PROCEED?

If you see this message or a request for a reboot, our advice is to stop the tracing process, and save the log with Revo Uninstaller Pro (on a system restart if the tracing of Revo Uninstaller Pro is active, then it will save the log with a default name automatically), and now restart your computer. For most programs, you will have a reliable log file, as in such cases all the program data is already installed, and the program needs a reboot to start its services or modules that are going to be started on every Windows start up.

HOW TO UNINSTALL A PROGRAM IF I SEE THAT THERE IS A LOG FOR THAT PROGRAM IN THE LOGS DATABASE?

Uninstalling a program using a log from the Logs Database is the same as if you uninstall this program using your own log. Just select the program in the Logs Database list, and click the Uninstall button. This will automatically download the selected log, import it in Revo Uninstaller Pro, and start the uninstallation procedure.

IS THERE A WAY TO UNDO AN UNINSTALLATION OF A PROGRAM?

Reinstalling the program is the first and easiest solution. Other options are to use Windows Restore or the Backup system of Revo Uninstaller Pro.

HOW CAN I STOP/REMOVE A PROGRAM FROM THE WINDOWS SYSTEM TRAY?

You can use the command “Kill” or Kill and Delete” of Hunter Mode feature.

WHY CAN’T I UNINSTALL PROGRAMS WITHOUT ADMIN RIGHTS ON WINDOWS VISTA/7/8/10/11?

Because uninstalling programs involves removing files, folders, and Registry entries from various protected system locations on your hard drive and Registry. The standard user account is designed to only have privileges to run/use most programs.

HOW CAN I REMOVE A PROGRAM, WHICH WHEN I TRY TO UNINSTALL USING PROGRAMS AND FEATURE OR REVO UNINSTALLER PRO, I SEE THE SAME ERROR MESSAGE?

Most likely, this error message is generated by the built-in uninstaller of the program you want to uninstall, which both the Programs and Features applet and Revo Uninstaller Pro try to run during the selected uninstall procedure. In most cases, Revo Uninstaller Pro can handle the uninstall process even if the built-in uninstaller of the program is not functioning properly. In that case, you should start the uninstall procedure with Revo Uninstaller as usual, and when you see that error message, you can simply skip (ignore) it, click the Scan button to start scanning for the leftovers of the program, and then continue as normal.

HOW CAN I REMOVE A PROGRAM, WHICH IS NOT LISTED IN PROGRAMS AND FEATURES (ADD OR REMOVE PROGRAMS) OR REVO UNINSTALLER PRO?

If the program is not listed in Revo Uninstaller Pro, then try our Forced Uninstall feature.

HOW DO I PROCEED IF THE PROGRAM’S OWN BUILT-IN UNINSTALLER ASKS TO REBOOT THE COMPUTER DURING AN UNINSTALL PROCEDURE?

The best approach is to decline the reboot request, continue the uninstall procedure as normal, and then finally reboot your computer. If you were unable to decline the reboot request, and your computer restarts, don’t worry. The next time you start Revo Uninstaller Pro it will prompt you to continue the uninstall process.

I UNINSTALLED A PROGRAM WITH REVO UNINSTALLER PRO BUT THERE ARE STILL LEFTOVERS.

Some files may not be deleted immediately if they are in use by another process. Such files are scheduled for deletion upon reboot so please restart your computer. If the leftover are still present, please try our Forced Uninstall feature

CAN I USE REVO UNINSTALLER PRO TO UNINSTALL ACCUMULATED UPDATES FOR MICROSOFT WINDOWS?

If any updates are listed in Revo Uninstaller Pro, then you should be able to uninstall them without issue. However, their installation and removal is extremely critical for the operating system, and it should be handled only by the built-in functionality in Windows.

I USED PROGRAMS AND FEATURE APPLICATION TO UNINSTALL A PROGRAM SEVERAL MONTHS AGO. CAN REVO UNINSTALLER PRO STILL FIND POSSIBLE LEFTOVER ITEMS SO I CAN DELETE THEM?

If already uninstalled, please try our Forced Uninstall procedure.

I AM TRYING TO UNINSTALL A PROGRAM, BUT DURING THE UNINSTALLATION PROCEDURE, THE BUILT-IN UNINSTALLER OF THE PROGRAM IS REINSTALLING/REPAIRING IT INSTEAD OF UNINSTALLING IT. HOW DO I PROCEED?

Please use our Forced MSI Uninstall feature.

I AM TRYING TO UNINSTALL A PROGRAM BUT ITS BUILT-IN UNINSTALLER’S WINDOW DOES NOT APPEAR OR START WHEN IT IS SUPPOSED TO START AFTER I CLICK THE UNINSTALL BUTTON?

If built-in uninstaller of a program does not appear, please check if its window isn’t underneath other windows that you may have opened, as sometimes uninstallations are launched in the background. You can check the Taskbar for any newly appeared windows.

If the built-in uninstaller doesn’t start properly and you see an error message, most likely, it is generated by the built-in uninstaller of the program you want to uninstall, which both the Apps and Features applet and Revo Uninstaller try to run during the uninstallation procedure. In most cases Revo Uninstaller can handle the uninstallation process even if the built-in uninstaller of the program is not functioning properly. In that case, you should continue the uninstallation procedure with Revo Uninstaller as usual, and when you see that error message, you can simply skip (ignore) it, click the Scan button to start scanning for the leftovers of the program, and then continue as normal.

WHAT IS THE LOGS DATABASE?

This is a database of logs of traced programs through the monitoring module of Revo Uninstaller Pro. The Logs Database is created and maintained by Revo Uninstaller Pro’s team. The logs are stored on our web server, and you can use them to uninstall programs or to remove leftovers of previously uninstalled program.

HOW TO UNINSTALL A PROGRAM IF I SEE THAT THERE IS A LOG FOR THAT PROGRAM IN THE LOGS DATABASE?

Uninstalling a program using a log from the Logs Database is the same as using your own log. Just select the program in the Logs Database list, and click the Uninstall button. This will automatically download the selected log, import it in Revo Uninstaller Pro, and start the uninstallation procedure.

CAN I USE A LOG FROM THE LOGS DATABASE TO UNINSTALL A DIFFERENT VERSION OF THE PROGRAM FROM THE LOG?

It depends on the program, and how much it has changed across different versions. In most cases, you should be able to properly uninstall a program with a version similar to the one of the log. For example, if you have Skype 5.2 installed on your computer, you should be able to uninstall it properly even using a log for Skype 5.1. That is because of the “Advanced Uninstall” technology applied when a traced program is uninstalled through a log. It searches for data related to the uninstalled program that may not have been recorded in the log.

HOW CAN I SCAN WITH THE JUNK FILES CLEANER FOR A SPECIFIC FILE TYPE?

Go to Menu button -> Options -> Junk Files Cleaner -> General, and check if the specific file type is in the list, and if it is checked. If the file extension is not listed, click the Add button, enter the specific file type in the newly appeared window, and click OK to confirm. Start the Junk Files Cleaner, and click the Scan button to start scanning.

HOW CAN I STOP PROGRAMS THAT START AUTOMATICALLY ON WINDOWS STARTUP?

In the Autorun Manager, you have to uncheck the program you want to disable. Conversely, to enable it, simply check it back again.
