TortoiseGit cannot find libcurl-4.dll

After recent switch to Windows 7 x64 TortoiseGit stopped working for me. Symptoms are non-descriptive – when you try to “Create a new repository here” it just shows error box with no text.

I had two suspects: some obscure configuration settings of TortoiseGit itself or msysgit, or missing library. So after quick upgrade to latest 1.1.1.0-64bit version it was time to run ProcessMonitor.

ProcessMonitor immediately showed that after some activity git starts looking for libcurl-4.dll in all possible locations starting with C:\msysgit\bin where I have msysgit installed, and fails. It appears that this library is in another folder: C:\msysgit\mingw\bin. I did not try to understand why, just added both folders to system path and voila! It worked. Setting dialog shows git version again, repositories get created.

Hope this helps someone.
