I'll try to do some research on polish site of the developer (gram.pl) to help You.
EDIT:
I do not know if this problem was written in english anywhere so i'm translating:
1. Uninstall CloneCD, Alcohol, Daemon-Tools
2. Restart computer
3. uninstall STPD
To uninstall it download this:
http://www.duplexsecure.com/download...t-v150-x86.exe
Run it and choose UNINSTALL (Do not install it again)
4. restart computer
5. Regedit.exe
6. Delete the registry keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Uninstall\{E9F81423-211E-46B6-9AE0-38568BC5CF6F}
HKEY_CLASSES_ROOT\Installer\Products\32418F9EE1126 B64A90E8365B85CFCF6
7. In device manager delete these devices:
SCSI & RAID --> A347SCSI SCSI Controller
System devices --> Plug & Play BIOS Extension
8. regedit.exe again
9. Delete these keys now:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\a347scsi
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\a347bus
10. Go to C:\Windows\system32 and delete these files:
a347scsi.sys
a347bus.sys
11. restart computer
12. I hope it will work
These are from official CD Projekt website. I hope these are helpful, and will work. Here is a link also in my language:
