HPSIM unable to upgrade from 7.1 to 7.2

[Pber]

I'm trying to upgrade from HPSIM from 7.1 to 7.2.  The setup gets to the database configuration screen but it only allows me to edit the username and password and all the other fields are locked.  When I click Next it errors with the message: "The Domain name has not been specified."    However since the domain field is locked I can't add anything to that field.

I've never had an issue upgrading before.  Any ideas?
