DT Lite 4.49.1 cannot create drives in Win8.1

[NickTesla]

I get an popup message that says the drive cannot be created when I attempt to create both the DT and SCSI drives. The drives do not show up on on the DT program, but when I go to device manager they are there under the DVD/CD-ROM devices catagory with a warning symbol next to it as if the driver is not working correctly.

I'm wondering if the new DT versions are even optimized for Windows 8.1 and if this is a common issue. I'm also wondering if there's anything I can do. This problem occurs on both my PC and laptop, both running Windows 8.1. Thank you.

Please try to manually delete upper/lower filter as described here (Resolution):
The CD drive or the DVD drive does not work as expected on a computer that is running Windows Vista (also works on Windows XP/7/8/8.1).
