I have tried installing the latest SPTD driver and still get the same message.
I think the SPDT driver doesn't work on Vista Ultimate. Afeter I install it and reboot when I run again SPTDinst-v142-x86.exe I get the message No SPDT driver detected and the Install option.
After that, I found this thread:
http://www.daemon-tools.cc/dtcc/showthread.php?t=11666. I deleted the registry key and now the daemon tools setup keeps promptimg for reboot endlessly ( the first step) and when I run the SPTDinst-v142-x86.exe I get the message "You Must Reboot after previous operation".
It is very frustrating and it's a problem on Vista Ultimate. I have installed early this afternoon the DT on Vista Business and worked like a charm. It also worked about 1 month ago on Ultimate. Since the there were some updates to Vista Ultimate regarding Application compatibility issues and I think that there are some problems.
I am just guessing. Here are the infos on the update for Vista Ultimate:
Update for Windows Vista (KB929427)

Thanks a lot. I can't wait to use DT on my computer again. I just can't live without it.
