Working this problem for the Planner 4.2 release (TheSky X compatibility). I have it installing on Win7 32 and 64 with UAC turned on. There are issues with TheSky X 10.1.9 which Bisque is working on. Once 10.1.10 is out I'll release a 4.2 beta. I have a test build from Bisque that corrects the two biggest TheSky X problems, the other two are installation problems with TheSky X (which can be corrected manually by the user but one is tricky).
