Frequently asked questions (FAQ)


The best approach is to decline the reboot request, search for leftovers with Revo Uninstaller Pro, delete any leftovers you deem unnecessary, and then finally reboot your computer. If you are unable to decline the reboot request and the computer restarts, the next time you start Revo Uninstaller Pro it will prompt you to continue the uninstallation process.

The main differences between them concern their types of licensing and portability.

The standard version has a license that is per computer. This means that it is purchased for a certain number of computers, but any user who uses those computers is allowed to use Revo Uninstaller Pro. The portable version has a license per user. This means that one user is allowed to use Revo Uninstaller Pro on an unlimited number of computers (but 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 the Registry on which it is run. That way, you can have a copy of the program with you.

We do not recommend uninstalling version 3 or 4 of Revo Uninstaller Pro before installing version 5 because you will lose your current settings and other user data. The best approach is to install the new version over the existing version, as it will overwrite it, and you will keep your data and settings, just as with minor updates.

If you are requested to restart your computer, we advise you to stop the tracing process, save the log with Revo Uninstaller Pro, and restart your computer — on a system restart, it will save the log with a default name automatically if the tracing of Revo Uninstaller Pro is active.

For most programs, you will have a reliable log file, as all the program data is already installed, and the program needs a reboot in order to start the services or modules that are started on every Windows startup.

These versions of Revo Uninstaller – Freeware and Pro – are installed in different folders and are completely independent. They do not share common components or modules. So, it is not a problem if you install the Pro version while the Freeware is still on your system. However, the Pro version is superior, so you will not need the Freeware version afterward.

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.

Alternatively, you can continue using your already purchased version without time limitations.

You choose the number during purchase.

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 can buy additional licenses at a discount.

You need a license for only one computer, as all your Windows installations are on the same computer. You should not have problems registering the program on any of the supported versions of Windows.

Before attempting to uninstall a program, make sure it is not running and is closed.

Select the program in Revo Uninstaller Pro, and click the Uninstall button. Revo Uninstaller Pro will start the uninstall wizard, which will guide you through the process.

Revo Uninstaller Pro will try to run the built-in uninstaller of the program you want to uninstall; let it finish. If it is not working properly, you can skip (ignore) it. Then you should proceed to the leftover scan by clicking "Scan". After the scanning finishes, Revo Uninstaller Pro will list all leftover Registry entries, files, and folders for you to review, verify, and delete.

If you have monitored an installation with Revo Uninstaller Pro, the best approach for removing it is to use the created trace log. To access that, open the Traced Programs module.

Before uninstalling a program, make sure 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 any of those icons are there, try right-clicking them, and look for an option like “Exit”, “Quit” or something similar.

Select the program in Revo Uninstaller Pro and click the Uninstall button. A window will display, showing the progress of the operation, and when that window closes, the program will be uninstalled.

If an additional window called “Advanced Uninstall” is displayed, you can use the same suggested method to scan, review, and remove any leftovers you find.

Uninstalling a program using a log from the Logs Database is done the same way as uninstalling the 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 into Revo Uninstaller Pro, and start the uninstallation procedure.

Reinstalling the program is the best and easiest solution using a setup file or installation media.

By default, Revo Uninstaller Pro moves all leftover files to the Recycle Bin when you delete them, so check there for accidentally deleted files. Also, by default, Revo Uninstaller Pro backs up every deleted leftover Registry item, so check the Backup Manager for any backups of deleted Registry entries you want to restore.

Revo Uninstaller Pro has a unique feature called "Hunter Mode":

  1. Switch to "Hunter Mode" — a blue window with a crosshair will appear in the screen’s upper right corner.
  2. Drag (holding the left mouse button) the blue target window to the system tray, and locate the program you wish to remove.
  3. Drop (releasing the left mouse button) on the target, and a menu will appear.

Then you can select "Kill Process", and it will disappear from the system tray. There are other options you may want to use such as: Uninstall, Stop Auto Starting, Properties, Open Containing Folder, etc.

You cannot uninstall programs if you do not have administrator privileges 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 only to have privileges to run/use most programs.

Most likely, this error message is generated by the program’s built-in uninstaller due to its being corrupted or not properly working.

In most cases, Revo Uninstaller Pro can handle the uninstallation process even if the built-in program uninstaller is not functioning properly. For that, start the uninstallation procedure with Revo Uninstaller as usual, and when you see that error message, simply skip (ignore) it, click the Scan button to start scanning for the program’s leftovers and continue to review and delete any leftover data you find.

If the program is not listed in Revo Uninstaller Pro, you can use our Forced Uninstall feature, which does not require a program to be installed or listed properly. Start the Forced Uninstall feature, enter the program’s exact name, and/or point to its folder on the hard drive, and proceed with the uninstall procedure.

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

You can use our Forced Uninstall feature, which does not require a program to be installed or listed properly. Start the Forced Uninstall feature, enter the program’s exact name and/or point to its folder on the hard drive, and proceed with the uninstall procedure.

Cancel the built-in program uninstaller and the uninstall wizard of Revo Uninstaller Pro. Then, in the list of installed programs, right-click the program in question and select the Forced MSI Uninstall command, which will start the uninstall procedure again — but the built-in uninstaller will try to uninstall the program instead of repairing it.


The Logs Database is a set of pre-created trace logs by our agents, accessible via Revo Uninstaller Pro, including popular or requested software products.

It is created and maintained by the 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 programs.

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 into Revo Uninstaller Pro, and start the uninstallation procedure.

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 on 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 the "Advanced Uninstall" technology applies 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.


Click the 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.

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