No Driver Found problem

[Silpheed12]

When I run the installation for DTLite4454-0315 on my Windows 7 64-bit, the installation stops at the "Updating virtual devices" stage. Windows tries to install the "DTSOFT Virtual CdRom Device", but after a long while of searching for a windows update, it'll say "No Driver Found."

Now, when I run it anyway under the free license and try to add a SCSI drive, I get the Daemon Tools Pro driver error: -1 message. When I try to add a DT drive, it'll try to install the DTSOFT device again, and fail again. Can I please get some help getting this to work?
