Hi Dscho,

I've installed Git for Windows 2.27.0 rc0 in my $work_machine today, I've run into this error during installation:

	Cannot create file "<my %localappdata%>\Programs\Git\dev\fd".
	Access is denied.

I have GfW 2.19.0 installed (by IT policy) in "%programfiles%\Git", and GfW 2.26.2 installed in %localappdata%\Programs\Git. I don't have the right to install software in my $work_machine

I can still use git-bash (by double-click git-bash.exe) after installation, though.

If you want more information, please tell me, I'll try to get it, tomorrow.

My Windows machine is only used to run Ubuntu in a Virtual Box. My limited exposure to GfW doesn't have any trouble. My normal vim usage in GfW's git-bash works pretty well. FWIW, I don't use arrow keys with vim.

Is there anything that you would like to have a cross-check, I can check during my free time, I can't promise much since I mostly work inside my Ubuntu virtual machine.
