Problem upgrading from Vista Home to Ultimate

[mocha]

I have my Daemon Tool working fine in my vista home basic
however, after i upgraded it to ultimate last night, i can't use daemon tool anymore
and then i tried to install dt , but it fails too, keep on asking me to reboot..never stops
i tried to download SPTDinst-v143-x86, same thing happen, keep on asking me to reboot
i accidentally deleted the sptd registry..
it says no sptd version was detected when i run SPTDinst-v143-x86 now..
and when i install it, it says failed to open service key...
i don't know what to do..please help
btw, for some reasons, i can't uninstall my daemon tool too

Don't use v1.43 anymore, install v1.45:

Execute regedit and check permissions of HKEY_LOCAL_MACHINE\CurrentControlSet\Services hive, System needs full access.
And check system eventlog (execute eventvwr.msc) regarding error messages of SPTD layer, post the entire error message including all binary bytes.

after setting the permission of the whole service thing
i was able to install 1.45
i can install dt after rebooting
