So, if you don't know exactly what to do, you might end up reinstalling the operating system. I am saying this because a lot of the things you will have to do to re-enable the driver for the old copy protection are done in PowerShell. It takes someone with a pretty decent knowledge of how an operating system works. The method to bypass all that marvelous blocking is kind of convoluted and way too complicated for a casual or even a normal user. If you are on Windows 10, if my memory serves me well, disc 1 was the one that would install the copy protection. Plus it's easier to re-enable copy protection support (though my wild guess is that you are on Windows 10) If you are still on Windows 7 - 8.1, you can still install that from discs, provided that you find another copy (Amazon still has some, but they are usually expensive).
The disc installation is fragged due to the copy protection and the fact that Microsoft decided that the old copy protections are a security risk and removed the drivers and proactively prevent them from installing (we are talking Windows 10 here).
