It instals a "virtual CD drive on your hard drive" The idea is for copying a CD to the Hard drive and run the "virtual copy" from the hard drive ideal for certain games and stops the CD from wearing out. Copies of CDs can be "mounted" in the Virtual drive
However Certain CDs have copywrite protection that will see the "virtual drive" and refuse to run the program.
I suggest you Unistall the virtual CD program - reboot the PC and then retry your CD.
