I've made up my first custom install. After installation it crashes during geoprocessing function Calculate Field with this return message:

Executing: CalculateField lyr value 10 VB #
Start Time: Tue Jan 22 17:22:16 2013
General error executing calculator.
ERROR 999999: Error executing function.
The operation could not be completed because the script engine has not been initialized to a valid language.
Failed to execute (CalculateField).
Failed at Tue Jan 22 17:22:16 2013 (Elapsed Time: 0,00 seconds)

I use VB.NET, Visual Studio 2010, W7, ArcGIS 10.1... What did I miss? Any ideas?

Thanks for response!
