I am not an expert, but I got this mod to work on vista. I do have Gold edition. I renamed the directory from My Creative Assembly to Activision. I then moved the file from Program Files folder to Programs. Everything installed and works fine. It eliminated the problems I was receiving on an inability to install the files. The problem I have on Vista seems mostly just to be that Vista is using different names for things ie Prgram Files in place of Programs, Programs and features a sthe name to Uninstall etc etc. Hope this helps someone.
