Thanks for the replies. I installed on a friends computer with WinXP to get the registry settings but have no success patching as yet.
I can get Benny's launcher to install by adding the registry keys. I cannot yet get the patch to run in the same manner. It seems Benny's launcher is searching for different keys to which the patch is searching for. Hopefully with some persistence I can still get this working but I'm running out of ideas fast.
Unfortunately, Benny's launcher crashes at the same point during installing the patch. His site mentions creating a new installer which could be a solution for the future.
If I get it working I'll be posting the workaround here. Nice site BTW.
