Error: Cannot Spawn C:\Path To\TortoiseGit\Bin: No such file or directory

Set environment variable GIT_SSH to

%ProgramFiles(x86)%\PuTTY\plink.exe

or

%ProgramFiles%\PuTTY\plink.exe

This blog would seem to be the exact same problem that you have:

And this issue on msysgit also points to the same error:

Find out what your GIT_SSH environmental variable is pointing to and if that path has a space in it. Maybe reinstalling TortoiseGit would solve it. (Otherwise I can really recommend GitExtensions instead)

For me the answer was removing the double quotes of "c:\Program Files (x86)\PuTTY\plink.exe" from the environment variable GIT_SSH.
