Yup, almost the same issue. And also an upgrade first that did not work.
Got new download and key. But...
"Your activation key is incorrect.
Please try again. (0x80ab000b) "
And trying again does not help (second day now, waiting for support answer).

Sorry to hear that. the person on the forum was very helpful and tried to give me other keys but in the end I had to go for a refund. Its a pitty reallly but my version 7 works fine. Maybe when I build a new Windows 7 PC (which will be soon) I will try and buy the correct upgrade and give it another try!

Well, note that I am running Windows 7 Ultimate (proper, not beta or RC).
You can get it now through technet or MSDN, or other MS partner deals.
Maybe cyberlink have only tried the code that does activation on beta and RC versions and something changed. If that is the problem then cyberlink will probably fix it when win7 is released to consumers. Against that cyberlink being developers themselves are probably running the most up to date version.

It seems like an infinite loop with Cyberlink "Support". They keep sending me a new key and a download link to a an program install every time I tell them that the activation does not work.
And it does not activate after reinstalling. Before install you have to uninstall powerdvd (seems to work fine, leaves no trace in program menu and control panel) but also manually remove some Registry keys and then som filesystem directories and files as per instructions. Whatever, it just does not work.

There seems to be no reflection over the fact that I have already done this X amount of times. Just send new key. UGH!

Well, hoping I can get I refund, I am tired of this so-called support.

well that is what happened to me, hence the refund. Just plain crazy really

Ah, but the loop was not so infinite as I thought.
They reverted the executable sent in the support answer to an older version of PowerDVD 9. Namely version 1501 (and that installed and activated ok on windows 7).

I am having this issue right now!! I purchased an upgrade from 7 to 9 Ultra and it did not work as the file was corrupt.

They gave me the 1501 full download for 9 and gave me the CD key...The program installed perfectly BUT the CD key while installing says that it is invalid and Support just keeps sending me the same information!??

Is this a firewall issue or something else? Support says that the key works perfectly fine!? I am at a loss now...$ and frustration!??

Yeah their activation code is out of whack. Feels like its the luck of the draw if it actually activates. Maybe you will have better luck installing with a later full version. Like the 1719 version they sent to me which did not work for me. Might work for you.
Are you running RTM (as opposed to beta or RC)?
