Found this and it worked for me...sort of after a little regedit
Please open the registry editor (Start->Run->regedit) and move to the
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\ area (by clicking on this
folder, you will see all the entries on the right side). Look at the
entries with an alpha designation (ie: \DosDevices\Letter_Here). You should
see one of entries with letters with duplicate entries. If you delete the
duplicate entry (right mouse click and choose 'Delete' from the choices),
you should be able to exit RegEdit and launch your program.
If the problem persists, please delete all REG_BINARY entries in this
folder (only blue ones on the right side). Reboot your computer
immediately, the entries will be re-established, and the game should start.
I had to delete all my Reg-Binary entries...then it incorrectly named the drives so I had to go back into the registry and manually rename the drive letters. Which was just a matter of changing \DosDevices\D: to \DosDevices\E: and visa versa.
