Recently, Revo Uninstaller 2.0 was released with full 64-bit support and came with an option to export the list of installed programs to a text or html file. Apart from the new features, the free version of Revo displays Pro version ad in the interface on the right side which is hard to disable. Today, VS Revo group has released a new update Revo Uninstaller 2.0.1 that is available without the ad panel. This version comes with fixes to minor bugs and updated language files.
Do note though the ad has been removed, the company still displays upgrade to Revo Uninstaller Pro link at the bottom, on the status bar, which leads to Pro version purchase page.
You can download Revo Uninstaller 2.0.1 (free version) from here.
