So im upgrading to R2. When i get to the Reporting Services Authentication step i get the error:

There are validation errors on this page. Click ok to close this dialog box. Review errors at the bottom of the setup page, then provide valid parameters or Click Help for more information.

Use the Reporting Services Configuration tool to configure the database source name (DSN) and connect to the database.

What i see is the instance field is blank. I don't know what to do here.

  • And i got a down vote! Why?

I got around this by cancelling the upgrade. Uninstalling the Reporting Service feature. When i reran the upgrade it didnt have this step.
