ARRGH!!! FS2004 Not Installing after Windows 7 rebuild

So I rebuilt my Windows 7 computer (major problems, don't ask)... anyway, I'm now attempting to re-install FS2004 but to no avail. It keeps having problems with Disk4 installing some of the CAB files for say, Atlanta, Paris, etc. I know that this is no longer supported by Microsoft so does anybody have any ideas? I've tried to clean the disk with a professional type CD/DVD cleaning kit and tried the 'toothpaste' trick but still nothing. Anybody know where I can just grab the missing CAB files that I need and then when I reinstall, I'll just choose the SKIP for these files and install them afterwards.
Any serious responses will be accepted. Thanks in advance.

ps - Disk 4 was working to start the game prior to having to rebuild the computer. Thanks.
