Can anyone out there help? I've confused a quite a few tech supports on this one... I have C&C TFD and it used to fully work on XP. Now I've bought a desktop and a laptop that already has Vista on them. Now all games except Generals and Zero Hour will run on Vista. I have two of the same disc (both originals) and both discs do the same thing on both Vista machines. Tried all the basics stuff (safe mode install, administrator tweaks, updates, drivers, firmwares...). Now the weird part: if I use an external dvd drive, the game works perfectly. The external drive is older than either the laptop or desktop. So I believe the trick to getting the game to work is figuring out why it works on the external drive. The game was NOT installed using the external drive and I don't have any emulation software that I'm aware of. Any ideas?
Here's a little more about the issue...
* I own two discs both worked on a no longer owned XP
* the game is command and conquer the first decade, the only game that won't play is generals and zero hour
* first always got "insert correct CD" when trying to play Tiberian Sun, Generals, and Zero Hour
* found that if I go to "games" and use the shortcut installed there, Tiberian Sun will play normally, but Generals and Zero Hour doesn't install any shortcuts
* after a mix of some of the fixes I will mention, Generals stopped prompting to "insert correct CD" and just disappears after the splash screen (in safe mode I was given the crash info included a few emails below)
* neither disc will play generals or zero hour on my vista laptop or vista desktop
* the game, including Generals and Zero hour will play if its through an external dvd drive (but of course I don't intend to attach an external dvd drive to a laptop which is what I use primarily)
* both the laptop and the desktop far exceed the requirments of the game, and the internal dvd drives in the desktop and the laptop are new and exceed the specs of the external drive that does play the games
* all patches are installed
* all drivers are up to date
* manually uninstalled the game and then reinstalled it using safe mode
* manually uninstalled the game and then reinstalled using a new administrator account after deleting the old administrator account so they wouldn't conflict with each other
* I've done all these steps running as administrator and in compatability mode and in every possible combination
* found a safedisc download and used it even though it wasn't where your support documents on your website said it would be
* looked on chat forums and found something about an option.ini file being in the wrong place and tried to create and fix that
* upgraded to vista sp1 and then re tried all steps
* I own the generals disk as the stand alone version and tried inputing it when was prompted in "insert correct CD"
* no emulation software exists in my computers that I'm aware of (Nero, Daemon... is there any others? Roxio movie creator came installed on the laptop, but I don't believe that's actually emulation....)
* dvd drive firmware is up to date
* video card drivers are up to date
* disabled DMA to switch to PIO (what ever that means....) and back again
* deleted lower drive filters and no upper drive filters existed to delete (what ever drive filters)
* closed one eye, crossed my fingers and toes, held my breath, and stood on my head.... with a partridge in a pear tree......
Hope that helps......
