[Edit: not a FSUIPC "installer" issue, appears to be related to having an install of RXP modules together with this latest version FSIUPC]
Grabbed what appeared to be the latest FSUIPC version (4.751).
Once installed (and re-registered), the problem generated is a message on FSX startup indicating a DLL (belonging to RXP GPS) is missing, dismissing that message leaves the FSX splash screen up, with the mouse circle twirling, and that is it. I expect the message is misleading in a sense, and just suggests that some setup file may have been munged.
I restored from a backup before the FSUIPC install, all is OK.
I didn't realize it was the FSUIPC install at this point, and reinstalled, and bingo exactly that same problem. There doesn't appear to be available just the .EXE to drop in the modules folder.
Win7 64bit, yes the installer was run "as administrator", and UAC is turned off.
Anyone see this?
