I played gta iv on my windows 7, windows 8 developer preview and on my windows 8 consumer preview,
but i wanted to download a save game so i used this one :
http://www.thegtaplace.com/downloads/f3542...00-pc-save-gamei had that file already installed on my other partition and it worked on 3 different windows versions,
here is an image:

I used the xlive that was inside the archive (again) but it didn't work,
do i need to install GFWL again?
Or can anyone give me a link of an working save?
