WinMerge on Windows 10: RightClick Compare does not work

In Windows 10, when using Windows Explorer, "Winmerge" context menu execution does not do anything. In other words, when clicking on the "WinMerge" option in the right-click contextual menu, nothing happens.

I've tried both WinMerge-2.16.0-x64-Setup.exe and WinMerge-2.16.0-Setup.exe

I have had the same problem. The solution for me was:

• Checking the box "Add WinMerge folder to your system path".
