I don't really know why the game couldn't find the CD ROM drive. That happens sometimes, and could be hard to track down.
The installers for a lot of older mods do not work with newer versions of Windows. Are you using Windows 7 or Windows 10 to install the mods? I can perhaps upload a new version of the installer that works.
