I can only guess you have other computer issues or maybe a bad CD (or bad download if you downloaded the CD installer file), or possibly both. I use the CD version and have 3 rentals. E-filed and accepted about 2 weeks ago with no issues.
If you downloaded the install file from a 3rd party retailer, might want to check with them if a fresh download doesn't help.
If you purchased the CD, there should be instructions somewhere in the package for how to download it directly from TTX without having to pay for it again. The instructions assume you don't have a CD drive. But should still allow you to download a fresh installer.
