I have installed alcohol 52% on my PC, although I am not able to use any virtual drives. No matter the amount of virtual drives I set up, none ever appear in my computer, and none are accessible via alcohol 52%. The virtual drives are just non-existent.

I have no security software or any antivirus, and I just made sure that I have no malware by running through the majorgeek forums step by step.

I have no idea what to do from here expect post my system information from alcohol and hope someone has a resolution.

Please go to Start -> Run and type regedit.exe and run it, then browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}, then please let me know exactly the values you have for the keys LowerFilters and UpperFilters.

Here is a screenshot. It seems the value for LowerFilters is PxHelp20, while I don't see upper filters anywhere.

After doing a small amount of research, I decided that when I uninstalled some disk burning software (I believe Nero), it had messed with the CD Drive registry. I deleted both the UpperFilters and LowerFilters entries, uninstalled Alcohol, rebooted and reinstalled. Everything is working perfectly.

Thanks for the info on where to look in the registry.

Thank you for letting us know.

I also have PXHelp20.sys (installed with Winamp for its burning engine) as the value of LowerFilters but no problems with Alcohol, so itself mustn't be the problem.
