Revo Uninstaller

As a last resort, Revo Uninstaller can be used to completely remove anything related to installed software. It is a third party program that can be used to remove all associated Little Green Button files. It’s a useful application if the above options fail.
This is recommended for advanced users only, such as IT staff.

Download the portable version of Revo Uninstaller here. This does not need installation, and will not leave anything behind on your computer after removing it.


Unzip the downloaded file and run the program. Once it's loaded up, click Little Green Button from the list and attempt to Uninstall.
Choose to Remove Little Green Button and click Finish.
If this process fails, Revo will now start scanning for any left behind files and components. Under Scanning modes, select Moderate (selected by default) then click Scan.

Scroll through the list of results to ensure only Little Green Button related results are present. This should be the case providing you did a Moderate Scan as opposed to an Advanced scan.
Click Select All, Delete, and confirm you want to delete all registry entries.

Do the same on the next screen and confirm you want to delete all left over files.

You are now finished, and Little Green Button is completely removed from your computer.
