OpManager won't start after update

Hi community,

after updating OpManager 7202 to 8006 it won't start any more!
Hangs at about 75%, "Configuration completed"

In the Forum I found possible hints, that it might be a problem, when running OpManager and ServiceDesk (7504) on the same server.

Please can you give me some suggestions to solve the problem??

thx
