I upgrade my zenworks primary servers (3) from 11.3.1 to 11.4 and then update the patch "Post 11SP4 Update Prereq" and finally update the primary server to 11.4.3.
All gone great, after I saw all primary server completed the update I remove from the "System Update" all old update and also the "Post 11SP4 Update Prereq" .
Then I was trying to deploy the 11.4.3 to all my satellite (in ver 11.3.1) and I got this message :
"The Update for ZENworks 11 SP4 (11.4.3) update requires the following update(s) to be downloaded and authorized before it can be deployed: Post 11SP4 Update Prereq"

I was trying to upload the "Post 11SP4 Update Prereq" to the server but still same issue

Any Idea ?
