Context menu not working if installed from non-elevated (non admin) user on win 10 x64

[denbkh]

Steps to reproduce:

1. create a new windows user in windows 10 x64, make it non admin
2. try to install WinMerge-2.16.46-x64-Setup.exe
3. admin elevation window shows up, enter admin pwd and install winmerge
4. right click on text file in explorer, select winmerge

Expected behavior: winmerge must run
Actual behavior: nothing happens

I have traced this in process monitor:

The problem can be fixed by changing the reg key value from "C:\Program Files (x86)\WinMerge\WinMergeU.exe" to "C:\Program Files\WinMerge\WinMergeU.exe". Therefore I think there is a bug in installation sequence.
Key location: HKCU\SOFTWARE\Thingamahoochie\WinMerge\Executable
