Sourcetree Won't Launch External Diff Tool :: Kdiff

[ibrar.mumtaz]

I have the same issue as:

https://community.atlassian.com/t5/Sourcetree-questions/Sourcetree-Won-t-Launch-External-Diff/qaq-p/1136586?tempId=eyJvaWRjX2NvbnNlbnRfbGFuZ3VhZ2VfdmVyc2lvbiI6IjIuMCIsIm9pZGNfY29uc2VudF9ncmFudGVkX2F0IjoxNTg4NTkyOTEwMjYwfQ%3D%3D

Difference is that:

- I don't have a Home environment variable.

- The ProcessViewer is telling me it is looking for my global git config file on the Q Drive. I don't have a Q Drive.

- When I load gitbash terminal, it is picking up all of my settings from my c drive userprofile location. Which is correct.

- I am using system git setting.

So I am at a loss here really, why I have lost 2 hrs to something that has always been working fine.

How do i force source tree to default to %USERPROFILE% instead of Q drive?
