I'm using Windows 7 64 bit and I've installed Zero Hour through The First Decade.
Now, initially I installed w/o compatibility & as admin and I got installation errors, naturally the game wouldnt launch... I got errors in the .bat file (access denied, that sort of thing and Zero Hour would launch instead.) I uninstalled TFD, ZH, TDR and started again with a clean slate.
I reinstalled, w/ compatiblity and as an admin - no installation errors.
Unfortunately, when using the launcher and as well the quick launcher - vanilla Zero Hour opens (w/o the animated beach battle background) instead of TDR.
I've set compatibility to XP SP2 for both launches and the installation respectfully.
When I run the launcher as admin, it just closes.
Any help or suggestions would be great, as I'm looking forward to playing. \o/
