Well I ran the setup again for the version of the SCS we are using (3.3.3)
First thing I ran into was the need for a database SA or equivalent account which was supplied the database team. Otherwise the setup will run to completion and then give an error requesting the need for correct DB permissions.
The setup then ran to completion, but with an error part way through where the service failed to update correctly. This left the install completed but without a functioning service.
I've now uninstalled the SCS using the AMTConfServer.exe and also Add/Remove programs. I'll let you know how I get on with the reinstall and redirection.
Also - does your Active Directory or other security items change from test to QA to production?
If so - might need to utilize the "database.exe" tool reference in the article
Hope that helps
