I uninstalled and installed the PowerDVD9 demo and it gives me the same error.
I uninstalled 9 and reinstalled the OEM version with the 8 Ultra patch (should be a little more obvious on which is my version). It seems to have gotten further than without the patch, but is still returning the above error. I was receiving a failed to register error on install but since installing the patch, that is gone.
It also keeps asking me for my region every time I try to play the blu ray disc.
I am running Windows 7 but have tried to run the program in various compatibility modes and receive the same message.
And I would upgrade except I get the same message with the PowerDVD9 I downloaded which doesn't make me too confident it will work.
Any help is greatly appreciated.
