Sorry to reply to such an old thread, but i got the same problem with a 4.6.2935 agent and vse 8.8..975.
It happend for workstation that are updating dat from the evaluation branch ( for pilot test ). Now im sure i got the right extension in epo. Is there a i should know about not being able to update from evaluation ? ( with that particular version on epo 4.6.4 )
I just tried something and it seems to work. My products versioning in my environnment is different than yours.
EPO: 4.5.0 service pack 6
VSE 8.7 patch 4 is in use
Goal: Test 8.7 patch 5 upgrade on selected systems.
After doin has you did for the small test group I found the followin error in my logs:
"Updates were not applied because the detection scripts were not found in the Current branch"
In my case, my EVAL BRANCH had only 2 packages in it.
- VSE8.7Pathch5 (full repack) --- This was checked in to test the FULL REDEPLOY of the latest version
- The stand-alone patch 5 for VSE 8.7 --- This is to UPGRADE our current production units that are on VSE 8.7 patch 4
I believe I was missing these packages in my EVAL BRANCH:
- Buffer Overflow DAT for VirusScan Enterprise
I copied the 3 later packages by going into the
Master Repository, Change branch> .... and selected COPY to Evaluation.
Re-ran the Task on the TEST HOST... so far it looks like it's working! Now I wonder if that is the offical McAfee way to go.
