Tutorial using CI 8.0.0

[BAMsE]

Damn Born_inSANE! Sorry man, but you're not nØØb, you're NØØB.

First. Use built-in attachement systen instead of mediafire.

Second. In your setup.ini

FreeArcFile1={src}\Data1.cab;C:\Program Files (x86)\Ubisoft:{app};Disk:1;PrecSrep:1

should be

FreeArcFile1={src}\Data1.cab;DestDir:{app};Disk:1;PrecSrep:1

What the hell for you changed DestDir to C:\Program Files (x86)\Ubisoft? DestDir is a variable and {app} is its value! Moreover, {app} means the path defined during installation.
So if someone want to install your Far Cry 2 to E:\Any_folder\Another_folder and type it during installation, then {app} means E:\Any_folder\Another_folder and Data1.cab will be extracted to E:\Any_folder\Another_folder
If Data1.cab should be extracted to any subfolder of installation path, i.e. Movies, then

FreeArcFile1={src}\Data1.cab;DestDir:{app}\Movies;Disk:1;PrecSrep:1

will extract content of Data1.cab to E:\Any_folder\Another_folder\Movies

Third.
