Oups, After re-read the help item, I have to repair FSX but not Acceleration... I try this. Christian

Hi Pete, I am encountering the same issue, after desinstall/install both FSX and Acceleration. Message is : Installer for FSUIPC4.DLL version 4.26 Looking in registry for FSX install path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Games\Flight Simulator\10.0 Parameter"SetupPath" SetupPath="D:\FSX\" 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) and FSUIPC4 Installer for FSX says : "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." I deleted first two directory named x86_Microsoft.FlightSimulator.SimConnect_67c7c14424d61b5b_10.0.xxx in the WinSxS directory, then repaired Acceleration. After that, always the same problem when I try to install FSUIPC4... Thanks for your help, Christian
