UPDATE I have found that Extensibility.dll is missing on client machine, so may be have sense install Extensibility libraries? I cannot find approriate installer for Extensibility.dll installation... So, does anybody know how to install Extensibility.dll on client machine?

I can only guess… Your client machine does not have Visual C++ runtime libraries installed. Check Windows logs for errors from Side by Side source.

If it is the case, you will have to run vcredist.exe for your version of Visual C++ before installing your plugin, or add merge modules to your MSI install package.
