Did you Run the regedit.exe as Administrator ?

If so, please specify full version number of DAEMON Tools and your Operating System version.
Please, send us the following files from your system:
- in case your system is Windows XP - find "C:\Windows\setupapi.log" file and sent it to us;
- in case your system is Windows 7 or Vista - find "C:\Windows\inf\setupapi.dev.log"

Sorry about my english.

As far as i can rate your log everything (regarding DAEMON Tools installation and system files) looks ok to me.
Would you please export the already mentioned reg key and attach/share it:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
