Installer For FSUIPC.DLL Ver 4.20

Recommended Posts

Good morning Mr, Dowson,

I have searched and reviewed prior posts; however I am still lost to the answer and fix to this problem.

Due to some glitchy FSX I recently did a full delete, DEFRAG and re-install of FSX and Acceleration. I attempted to install FSUIPC 4 and received the following:

Your FSX installation is incorrect! The version of SimConnect installed will not load FSUIPC4. You may need to repair the FSX installation to rectify this first.

No changes have been made by this program.

Looking in registry for FSX install path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Games\Flight Simulator\10.0


SetupPath="C:\Program Files\Microsoft Games\Microsoft Flight Simulator X\"

Checking version of FSX.EXE:

... Version 10.0.61637.0 (Need at least 10.0.60905.0)

Checking compatibility with installed SimConnect:

... Probe Manifest fails to match a valid base SimConnect needed to load FSUIPC4!

Found later build SimConnect 61242 (SP1 May07)

Found later build SimConnect 61259 (Acc/SP2 Oct07)

Ouch! That's one of the main cause of really bad SimConnect problems. It is not actually possible to properly uninstall the shared libraries for SimConnect, so when you reinstall it makes rather a hash of things. I hope Windows 7 sorts this out, but as it doesn't appear to be a problem for programs with proper uninstallers I suppose the Windows guys would blame the FSX uninstaller for being deficient.

Version 4.20 is pretty old now and certainly not supported. Please refer to the Announcements above for details of supported versions and get yourself updated.

You will probably still get the same error with 4.40. Really you will at some time need to repair your SimConnect installation (the FSX Help Announcement gives some guidance there), but it is really messy and you may end up having to re-install Windows too. However, because of some changes I've had to make to FSUIPC4 to make it work on ESP as well, after installing 4.40, the latest Update (4.435) from the Updates Announcement above may just manage to work on your messed-up installation. Other SimConnect clients may not, however.
