Where'd my drive go?

[Jack_Nasty]

Hi guys,

I installed the program and tried to mount some images and no drive appeared. The computer recognizes that the drive is there but doesn't recognize it as anything beyond a name. I checked my device manager and got a little yellow question mark next to the device name. This happened after I unknowingly upgraded to 4.03, I tried uninstalling and reinstalling, uninstalling and trying alcohol 120, same problem, then I uninstalled and put 3.47 back on with the same problem, so what am I doing wrong? What do I have to do to fix this?

Which device has yellow exclamation mark (SCSI controller or virtual cd/dvd device)? What kind of error is mentioned there?
Do you see any errors related to Daemon Tools in system eventlog (run eventvwr.msc)?

How did you "uknowingly upgrade" your DTools install? It's not like it has an auto-update function. You have to download and run the installer to update it....
