Today, I started to receive Daemon Tools driver error 55 when adding any kind of virtual drive. I tried both adding an IDE and an SCSI drive but none of them worked. I am currently using Daemon Tools Pro 8.30.

I am not sure what caused this issue, though. The last time I used a virtual drive happened a few weeks ago. Since then, I installed the update to DTP 8.30 and also installed a number of Windows updates during the latest patch day on May 14th. At the moment, I am still running Windows 10 version 1809 build 17763.529.

Is this issue known already? How can I fix it?
