Just remembered one other thing that is non standard. I removed all Parallels Access references, per instructions from Parallels support, when it was installed automatically by desktop 9. I do not use Access.
In case it is something to do with that I'm going to try to install 9 and then upgrade again with the Access nonsense in place.
Reinstalling Parallels 9 and applying the patch is working on Yosemite DP6. Installing Parallels 10 still fails even after that though.
DP7 of Yosemite popped up on my system today and I still can't install Parallels 10 after upgrading my system to Yosemite DP7
Eugene - any news from the Parallels team? This is dragging out a bit now with no new information.
