Sounds like you have either a problem with the RSD not installed in your Repo correctly or your task for deployment is pointing towards "nothing".
DId you recreate a new "install rsd" task?
As far as I can see, RSD is installed correctly in the Repo. It's in the current branch although because of the "issue" with 4.7.1. it shows as being an evaluation copy. I've tried removing the sensor package, restarting the server and then re-adding the sensor and there is no change. Adding the sensor into the "previous" branch as well, does not help.
I have also tried duplicating the "Install RSD" task and that makes no difference. It's not possible to delete and recreate the original task. There does not seem to be a way of checking that the "install RSD" task is looking at the version of RSD installed in the repository because it's not a standard client task.
I have also checked the RSD policy and it is all set correctly, though the install doesn't seem to get far enough for that to be relevant.
Hmm thats strange. The ability to create the RSD install task is only given when the RSD is in the repo. have you tried to delete the RSD package through the Software-Manager and Master-Repository?
How would it be to remove the RSD by hand?
Yes, I've tried deleting RSD via the Software Manager and/or from the master repository (we have no other repos at this time).
How would I delete it manually?
You should find the installpackages under: C:\Program Files (x86)\McAfee\ePolicy Orchestrator\DB\Software\Current\RSD_____4700
If you have it in a VM i would take a snapshot before removing as I am not 100% sure. Maybe you ask so from the McAfee-Support.
