We do not recommend you uninstall version 3 before installing the new version 4 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 it happens with minor updates.

The main differences between the standard (installable) and Portable versions of Revo Uninstaller Pro, are the licensing type and the portability of the Portable version. The licensing of the standard version is per computer, whereas for the Portable version it is per user. The standard version has a license that is per computer. This means that a license is purchased for a certain amount of computers but any user who uses those computers is also 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 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. That way you can have a copy of the program with you.

Both 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 have installed the Pro version while the Freeware is still on you system, but the Pro version is superior, so you will not need the Freeware version anymore.

The reason for this is that Windows 7 does not allow pinning programs containing the word "install" in their name. You can solve the 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.

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 detect them.

Revo Uninstaller Pro helps you remove the leftover registry keys, files, and folders after uninstalling an application.

If you see such message or 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 it will save the log with a default name automatically), and to 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 in order to start its services or modules that are going to be started on every Windows start up.

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.
