DB Problem during installation

Hello, during installations I'm getting an error
Setup failed: Specified cast is not valid.

I'm installing on hosting. using MSSQL server 2012.
I've created a fresh DB.

Could you, please help me with this one?

Hi,

Do you have custom modifications?

If you are using the source code version of nopCommerce you can run it in Debug (pres F5), do what you have done to cause the error and when the exception is thrown the VS (latest version) will automatically stop on the place where the exception have occurred, from there you will be able to see what exactly is the problem using the exception message and the stack trace.

If you are not able to figure it out yourself we will be happy to help, but we will require the stack trace and the exception message.

Best regards,
Iliyan

Thank you, for replay.
I'll try the local run and debug.
