"Git bash here" and "Git GUI here" not working on Windows 10

I just installed Git for Window version 2.18.0 64-bit on a new Windows 10 machine (Win 10 Enterprise).

When I right-click in explorer and choose 'Git Bash Here' or 'Git Gui Here' I see an 'Application Not Found' error pop up.

Update

I found this answer which nearly helped me find the problem and the solution.

With regedit I was able to see that the HKEY_CURRENT_USER\Software\Classes\Directory\shell\git_shell\command was pointing to my user folder, instead of the actual location of git:

For "Git Bash Here", I changed the value to "C:\Program Files (x86)\Git\git-bash.exe" "--cd=%1"

Similarly for "Git GUI here", I changed the value for the HKEY_CURRENT_USER\Software\Classes\Directory\shell\git_gui\command to "C:\Program Files (x86)\Git\cmd\git-gui.exe" "--working-dir" "%1"

However, I still see the 'Application Not Found' error. Any ideas how to fix this?

I'm not sure what caused it, but it looks like the installer put the application in the wrong place (C:\Program Files (x86)\ instead of C:\Program Files\) and set the registry paths wrong.

My solution was to completely uninstall, delete all related registry entries and then re-install. After that everything is working fine. I suspect a bug in the installer that is dependent on specific options being selected.
