HiI am using both FS9 and FSX+SP1Just purchased Radar Contact, arrived by mail yesterday. Installation went ok I think. After selecting plan, having set up options, rebuilt scenery data base I select Run-start RC i get the following error:"cannot link to FSUIPC or Wideclient"I have FSUIPC Version 3.7.4.0 for FS9I have FSUIPC Version 4.1.0.0 for FSXBoth versions are unregistered and are in correct module folders.I notice in C:Program Filesrcv4x folder that I can Install FSUIPC4.exe. When I activate .exe I am confronted by the following:Installer for FSUIPC4.DLL version 4.070Looking in registry for FSX install path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft GamesFlight Simulator10.0 Parameter"SetupPath"SetupPath="C:Program FilesMicrosoft GamesMicrosoft Flight Simulator X"Checking version of FSX.EXE:... Version 10.0.61355.0 (Need 10.0.60905.0)How do I overcome this problem as SPI for FSX requires my version I believe. Is my FS9 version ok.Your advice/assistance would be greatly appreciated.Regardsnoels7

do you have fs running, when you click the "start rc" button?is fsuipc on the modules (fs9) or addons (fsx) menus?jd
