I just bought Wavelab7 and have the same problem (“can’t change registry data”)
I tried running the *exe as administrator and that didn’t solve the problem.
I filed a support ticket and have been working with Jeff Deno–he thought it might
be a defective install disc and attempted to mail me another one, but it’s been over
a week and I haven’t received it.
I got the idea this morning to download the trial version to see if that works (I’ve already
successfully downloaded the license to my eLicenser, so it would likely come up
in non-demo mode). However, I’m still getting the same error even with the downloaded
trial version, so a new disc probably won’t help anyway.
The key that can’t be changed is HKCR.ogg\OpenWithProgIds
AB, did you ever get this resolved? Any/all help is appreciated!
