Service DellDRLogSvc is not running after Installtion of Rapid Recovery 6.2.1 Core an Agents

Yesterday, I installed the new core version 6.2.1 and the agent version. Now I got the problem, that the Service DellDRLogSvc is not running on each server, which I installed. I can't start it. I got the message: "Error 2: The system cannot find the file specified".

I made no other changes, so it should cause by 6.2.1 update.

The server running on WIN2008R2
