The error message “Couldn’t generate the upgrade script” pops up during configuration of Reporting Services for MS SQL Server 2005, if you install reporting services after installing a service pack – in my case Reporting Services was installed as SP1, while the main SQL Server 2005 install was updated to SP3.

Reinstalling SQL Server 2005 SP3 fixed it.
