OK time for the maybe stupid but obvious question ..... are you running (the installer) as administrator?
What he said. We should have asked this first.
Yes I did (at first). I do not remember if I was running as admin after taking ownership. Will try again. BTW - PGMusic tech guy suggested ignoring the error b/c CDRipper is non essential.
I also think that there should be an option to install at location of your choice - external or internal. No just supplied USB or C:\.
