Git GUI crashes every time it opens a repository

Question

Since few days ago, every time I start Git GUI in a repository, it displays this horrifying error message and quits after I click OK:

prepare-commit-msg hook fai         


        

Answer 1

I was getting this same issue after installing 1.8.0 on a Win64 machine. I solved the issue by removing 1.8.0 and installing 1.7.11
