Hi, I just purchased Rfactor 2, and I am trying to install the Ferrari 643 mod by ASR ver 1.2. I am using windows 8.1, I saved the download in my packages folder with the other ISI stuff. When I go to mod manager to install it is not there. the other mods from ISI worked for me but not this one. Can someone please walk me through how to install this mod please, I am very new to this thanks.
