I know it is a bit late now, but to bypass this issue, you can just deselect the vcredist 2008 SP1 from the download/install list at FitGirl repack installation, as that is not available on the website. You can easily install the game then, and if you want, you can use the following link to download and install the pack so the game will run perfectly fine:

look for that file in your antivirus and restore it from there then run the setup again
