Error finding tcl.init when running Git GUI

Question

I get the following error message when I try to start the Git GUI:

Error in Wish

Can't find a usable init.tcl in the following directories: ... [list of directories follows, init.tcl is in the first one listed]

This probably means that Tcl wasn't installed properly.

I'm running Windows 7 and I'm sure this problem is related to that, but I don't know where to start. I can, and most often will, use the Bash tool, but it annoys me that this doesn't work.

I installed the msysgit package: Git-1.7.0.2-preview20100309.exe

Answer 1

I have the same problem (win7 prof. 32bit) and just found out that everything runs as it should, as soon as I try running gitk as administrator.

Edit: it also helps to change permissions for git/bin/wish.exe to "always run as administrator", though it'll then ask for administrator credentials any time I run gitk.
