Error decompressing data. Corrupted installer?

[Krisios]

I recently purchased Knights of the Old Republic 1 & 2 (2 disk set). I have the first one installed but I get the error message- "Error decompressing data. Corrupted installer?" when I get to models.bif during the installation. I am currently using windows 8 (obviously) but the recommended specs for the games say windows 7. I do not know if this would effect the installation, if so is there a way for me to get windows 7? Any kind of feedback on my problem would be much appreciated. I would also like to apologize if I'm posting in the wrong sub-forum. I'm a little iffy on what the problem actually is.

Even just a simple- Sorry, we can't help will suffice as feedback at the moment.
