I'm trying to configure Git to use Plink. It worked for me many times before. Now, for some reason, this option isn't available to me (it is disabled):
I tried uninstalling and reinstalling Git a hundred times. Nothing. I can't get to this option enabled.
This is an old question, and I just have the same problem, just to be sure I will write down the solution that worked for me.
The msysgit installer didn't show the screen that allows to select between the openssh client and the Tortoise (plink)
The solution is to install Putty (or Tortoise Plink I guess), create and save at least one session, just installing Putty didn't work, the session must be created, the installer does some weird check about that.
When you run the Git installer again, the screen should appear.
