I am having this problem.
Unable to add adpater: Device problem 32
What should i do to reslove this?

I tried the following and was able to follow till step 4, at step 4 i wasnt able to delete the key. I corrected the key's permission but it still says "Error while deleting key". i tired to skip this part but ended up with problem 32 still.

I tried the following too.
"At step 4 set your user account as Owner and then correct key's permissions.
You will be able to change key's owner and permissions only if you uninstalled SPTD driver and restarted your system."

1. Uninstall DT via Start menu -> All Programs -> DAEMON Tools Lite -> Uninstall menu item. Or remove DT Lite folder.
2. Download SPTD driver setup from Disc-Tools.com - Published Software Download Uninstall SPTD using downloaded file.
3. Restart your system.
4.Start regedit.exe (standard system registry editor) and delete
"HKLM\System\CurrentControlSet\Services\sptd" key. Correct key's
permissions if it's necessary (via key's right-click menu).
5. Restart your computer.
6. Install DT.

Please help. Thank you.

Then either SPTD is still running (check Start value in that key) or you haven't set Owner and Full Access permissions.
