Hello Sir,
I resolve the above error by adding required assemblies. But now, i am getting anoter error at installation. Error generates when i am calling ConfigureDatabase() function, otherwise every thing is ok.
My error is...
The installer has encountered and unexpected error installing this package. This may indicate a problem with this package. The error code id 2869.
Here i attach my hole source code...
