Nobody can help me?
Unfortunately there are a number of things that can cause this type of error - I would recommend opening a case with Support so that we can anyalyse this properly.
Which patch version do You have installed ?
If older than 4.5 Patch 4 it wont update to 4.6.1.
I had the same issue upgrading.
Installation Patch 4 to 4.5 and then 4.6.1 works great.
Patch4 is already installed. I opened a ticket to Mcafee.
One thing to check, did you install patch 5 to 4.5 ?
It's another theory for upgrading to 4.6.1.
Let us know what McAfee support answer.
