General ISO Installation Problems

[EJinFullEffect]

Alright, folks. Here's a problem that's stumped many a Comp Sci major at my University. Hopefully somebody here has encountered this problem before, and can help me out, because boy is it frustrating

I am currently running a Dell rig. Here's just some general info.
Pentium IV 2.6 Processor
512 DDR RAM
128 MB ATI RADEON 9800 Vid Card
Sound Blaster Audigy 2 Sound Card

Here's the problem. A lot of the times, I will mount a game .ISO to a virtual drive using Daemon Tools, and then installed. The game goes all the way through installation, and even publishes product information. At the very last second, one of two things happens (depending on the game):

1. A message comes up on the installation window saying something along the lines of "The Installation was Interrupted. No Changes Were Made. Please Try Again."

OR

2. Installation just closes entirely with no message.

Nothing has been written to my hard drive after this happens, and no space is taken up. As far as I can remember, this has never happened with any non-ISO game, aside from one occassion. Doom III did the same thing, and it was on legit CD from EB Games.

Here's a list of games I've tried to install this way:

Age of Empires III
Call of Duty 2
Fable: The Lost Chapters
Quake IV

The same thing happens every single time. I've tried installing while not connected to the internet, installing in safe mode, and changing the virtual drive. It doesn't seem to be bad data either, as the same files install and run fine on my roommates' PC's.

Hopefully, somebody has seen this before!

Thanks in advance, guys!

Why not install it using the original? Then use the backups to play?

Do the same errors appear when using the originals? I know you said Doom 3 did. But how many more?


It could be your cd-roms laser is dirty or misaligned, try cleaning it and try again.

You checked for Virii/Spyware, I know it's an obvious thing but are you clean!!

Do you have anything running in the background like a disk defragger, backup progs? Check with Task Manager for any suspicious processes too, it just sounds like something is interfering with the install!
