Hi:
Which Vista edition do you have ? 32? or 64?
If 64: then you need to have it installed in the Program x86 directory.
You don't need to run as administrator.
You don't need any compatibility mode.
Video card drivers and Direct X are current ...right?
You do need enough memory. I wouldn't want to try with less than 4Gb but you might get by with 2. When the sims stops running open and check Task Manger to see if you are out of or very low on memory. chances are good that you are.
I just doesn't make sense that you can run anything but the tutorials...they are just "special" single missions. If you can run any single mission then the tutorials (Tutorials= SUB School..Right?) should run.
What mods have you installed? Any problem I have ever had with Vista/SH4 was mod related. Jerk the offending mod and SH4 goes back to running fine and dandy.
If you have 32 bit Vista then I don't know what to tell you. I never saw the point in 32 Vista...might as well have stayed with old XP.
Good luck!
