I thought it was common practice to post when the problem had been resolved.
So that anyone happening upon this thread would know that the problem has been resolved and suggestions need not be posted.
Glad you're sleeping well again. I know this must have been on your mind all day. Oh God, did that random internet toad fix its software dilemma?

I found a torrent that works. Problem solved, I guess. 

I recently switched from playing on my laptop to the desktop, because the laptop is a piece of shit.

I have the base game, University, and Nightlife on hard disk, but have been pirating the others.
I downloaded the image files for Open for Business from gamecopyworld as per usual. I can mount the .mds in Daemon Tools, but it tries to start by asking me to pick an image viewing program. Clicking the autorun .exe gives me: "The version of this file is not compatible with the version of Windows you're running."
I am running Windows 7, 32 bit.

I came here because I ran out of options. What do I do? Feel free to point out the inevitably obvious thing my retard brain missed.

Edit: It might be worth mentioning that all the files in the AutoRun folder appear to be bitmap images. What. I know this isn't a problem with the files because I tried several sources.
