Sticky: Side by side configuration error

(1/5) > >>

Hi all, I stumbled upon FSHost while looking for a better solution to the downright abysmal gamespy system on FSX. I downloaded the server side part of it, but when I went to open FSHost client it gives me the error: The application has failed to start because its side by side configuration is incorrect.". I saw Russel Gilbert's post on the simconnect not being installed, but when I opened the MSI file it started and then closed with no error. My C++ redistributable appears to be installed fine too. My friend downloaded FShost client as well and he has the same error while opening FShost client.

Thank you for your time

Russell Gilbert:

It seems like that error is usually related to the C++ Redistributable package. I'd suggest uninstalling it (Control Panel / "Add or Remove Programs" -- or "Programs and Features" in Win7) and then reinstalling it.

You can download the C++ installer here:

Microsoft Visual C++ 2005 SP1 Redistributable Package (32-bit) - Version 8.0.50727.762

Microsoft Visual C++ 2005 SP1 Redistributable Package (64-bit) - Version 8.0.50727.762

If that doesn't fix it, try looking in the Event Viewer just after installing the C++ package, to make sure it installed ok:

* In XP, go to Control Panel / "Performance and Maintenance" / "Administrative Tools" / "Event Viewer", then select Application. 
* In Win7, go to Control Panel / "System and Security" / "Administrative Tools" / "Event Viewer", then select Application.
The most recent entries are usually at the top.  Take note of when you ran the installer, and look for entries starting at that time.  On my Win7 machine, I see several entries with the Source name of "MsiInstaller", but the most important one is probably the one that has this info:

Product: Microsoft Visual C++ 2005 Redistributable -- Configuration completed successfully.

If FSHostClient still won't run, try reinstalling SimConnect, which is the communication system that comes with FSX, and allows FSHostClient to talk with FSX.

To do that, you'll need DVD #1 from the Deluxe version of FSX, since the Standard version doesn't include the SDK.  First shut down FSX and FSHostClient.  Then load the FSX DVD #1, go to the SDK directory on the DVD, and run setup.exe.  After installing the SDK, go to the following directory on your PC and run "SimConnect.msi":

C:\Program Files\Microsoft Games\Flight Simulator X SDK\SDK\Core Utilities Kit\SimConnect SDK\lib
or in Windows 7:
C:\Program Files (x86)\Microsoft Games\Flight Simulator X SDK\SDK\Core Utilities Kit\SimConnect SDK\lib

Then go back to the Event Viewer (see instructions above) and check for a successful install again. You may need to refresh or restart Event Viewer to see the latest entries.  Again, look for entries where the "Source" column says "MsiInstaller".  They should be near the top.  One of them should say:

Product: Microsoft Flight Simulator SimConnect Client v10.0.61259.0 -- Installation completed successfully.

Then try FSHostClient again.


Hi Russell, it appears I have about 7 copies of both the 2005 and 2008 redistributable, I will uninstall them all and let you know how it goes

When I try to run the FSHostclient.exe application, I get a side-by-side execution error, which produces this error entry in the event log. Any idea what could be causing this? I uninstalled and reinstalled MS VC++ 2005 Redistributable packages (both x86 and x64 versions) already. Any help would be appreciated.  Thanks

Activation context generation failed for "C:\Users\AviatorX60\Downloads\FSHost (FSX)\FSHostClient.exe". Dependent Assembly Microsoft.FlightSimulator.SimConnect,processorArchitecture="x86",publicKeyToken="67c7c14424d61b5b",type="win32",version="10.0.61259.0" could not be found. Please use sxstrace.exe for detailed diagnosis.

I get this error as well. Tried installing the file that was linked to and events manager reports it installed correctly. Yet the error remains the same.
