Thanks Guys...
This is a hard copy of X2 (DVD) which installed fine on my win7 machine...
I did re-run it (as administrator both times) with an uninstalle between of course... ;-)
I tried that before I posted...
Maybe I didn't have McAfee as turned off as I thought? I'll look some more.
It seems that all the problem items encountered were control surface dll's and a couple of 32bit v-synths. Sonar itself seems to be working fine so I'm ok... for now?
I had thought that maybe these had some win8 issues that were resolved with the win8 portion of the X2a update, but I guess not...
Thanks again... I'll try installing the 32bit version and see what happens...
