Not exactly a SimConnect problem, but is there a way to know inthe installer of an Flight Sim add-on whether the FS version on the user's machine machine is FS9, FSX RTM or FSX SP1? Are there registry keys that tell me this machine currently has the FSX SP1 installed?Is there an officially sanctioned way to determine the version?

This is entirely off the top of my head but you could use the win32 api to locate the file version of the exe which is buried into the standard exe header. The catch is to find the install folder. The registry should hold the setup path for FS9 or FSX. For versions older than FS9, I'm not sure. Sure, the blunt HDD search would help, and you may even fake the search by looking only in the default install paths, but that also has holes in it.Simconnect (FSX only) does give you the information provided it can connect to the server (ie, FS running) during the open event.Etienne

The open event is kind of late to get information for the installation process of the add-on ;-)I have to decide which executable to install in the first place. One version binds against the simconnect RTM version, the other binds against simconnect SP1.Christian

Christian-check your installer to see if it has Version check functions in there - the fsx.exe installed can tell you which version it is, using Win32 functions such as GetFileVersionInfo().If your installer does not allow external Win32 calls, you can make a DLL the way your installer likes, which, linked against Version.dll will be able to call GetFileVersionInfo() and check FSX.EXE for what you need.
