Hi there!

I have installed innovator 11 on windows 7.

Mircosoft SQL SERVER - 14.

Configured IIS from Built-in component of Windows 7 - IIS version is 7.5( as per Microsoft document )

IIS is correctly configured. I have created helloworld asp page and placed in in wwwroot just to be sure IIS runs smoothly and the asp page does run. 

.However when accessed localhost/.../InnovatorServer.aspx IIS throws the Error - 

This page isn’t working

localhost is currently unable to handle this request.

HTTP ERROR 500

Any help is highly appreciated. Thank you

Regards,
