in case anyone is wondering as i was left confused, i believe a step is missing .
Code:
3. Open InstallerScript.iss
Edit the following lines, according to the installation directory of the game.
#define SourcePath "C:\Program Files\Ubisoft\Assassin's Creed II"
4. Save and compile
I opened the iss file in notepad and edited the lines this way.
You need InstallerScript.iss (Inno Setup Compiler with Unicode). Edit the file in this program - save - Build - compile from the top menu.
Also this part 5. I believe you mean make a new folder and call it "Compiled," and then copy those files over into this new folder.
I also did not get the Redist Folder so i left it out. Install tested everything went perfect! 4.17 GB (4,485,234,688 bytes).
Thanks Man!
