That happens to be my favourite game, along with a heap of mods. I've been
running it without issue in just about every version, both x86 and x64,
since Beta 2 ;-)
My C&C ZH wont allow me to play online, messsage "Cannot connect to C&C
Generals Zero Hour"
Any tips/thoughts, I've allowed it full access through both windows and
McAfee fire walls still no joy. Please help.
I don't know if there are anything specific about the game installer, but
here are a couple of things to try:
Running as administrator and having admin rights are different on systems
with UAC enabled. Try right-clicking on the setup program and selecting
run-as-administrator.
Another possibility, try installing to a different folder, such as C:\GAMES
which works differently from c:\program files
