aha the two files you were refering to was in fact the nfo file as well as the Farcry.exe. The nfo file is not needed (even tho you should always read it!).
And yes like Barry has said you need to install the v1.3 update first then the v1.31 update. Then like Barry has also said you then copy the Farcry.exe to the 'bin32' folder overwriting the original file when asked to do so. Now you will be able to play without using the DVD/CD.
