[jmoberg]

When attempting to upgrade the subscriber to 3.1.3a from 3.1.3a I get the error, "Cannot continue because a valid a valid Callmanager installation could not be detected. Please install the Callmanager software before applying this update" I have verified that all of the correct Callmanager versions/services are running.

I have already upgraded the publisher to 3.1.3a with no issue. I have used the same 3.1.3a image to upgrade the subscriber that I used to upgrade the publisher.

The servers are MCS-7835's. What parameters is the update using to verify there is a Callmanager already loaded? Does any one know why it’s behaving like this, I just upgraded 5 Callmanagers to 3.1.3a without any problems but on the 6 and last server, it just won’t work.

Thanks in advance
