Check Prerequisites during Configure Scenario failed

Hello,

Solution Manager 7.1 SP03, patched to latest packages.

If I try to use the Managed System Configuration Wizard to configure a Scenario the Check Prerequisites step will fail with:

Error 
 LM-SERVICE 7.10 is not installed 
  Action 
 Please check SAP Note 1483508 for more information 
  Check Context 
 Diagnositics Prerequisite | Diagnostics prerequisite | SYSTEM =SOLMAN

But ... LM-Service IS installed: 7.10.3.1 .

How can I fix that issue?

Note 1483508 isn't helping. I did Step 1. and 2. ... but not 3, because "Turn off Maintenance Mode" and "Run Java Upgrader" isn't existing in 7.1 SP03 autoconf.

Note 1612514 isn't helping too, the patches mentioned there are already installed.
