nothing.

The application just ignores the user and takes a nap.

I did hear back from Intervideo after my last post (12 days and 2 requests). They basically gave me the clean reinstall directions again (see below). After, I got the same error - WinDVD Gold would not launch the Activation screen on my Windows XP Pro, SP2 system.
I did 2 additional things to make mine work. However, I feel like it was only the "Run As..." that really solved the issue:
1) After doing step 8 below (removing the install information folder), I went into the regedit and searched on this string. There were a few keys that contained this same install information. I deleted these keys from the registry also. Since I did this prior to copleting the remaining steps and I still had the problem after completing their instructions then I feel like this step did not really help. However, if the next step does not work for you then you may try this procedure also.
2) After following my step above and their directions below, I then followed advice from a prior post to create a new Administrator user "windvd". Then use "Run As..." from the right-click menu on the WinDVD 8 desktop icon to make it run as this new user. After doing this and launching WinDVD, I finally got the Activation screen and was able to activate the software. After this, the "Run as" user is no longer needed as it runs with my normal Power User id.
