Altiris Recovery Solution stop being able to deploy agents, all the same "Full permanent" licenses

Without the renewal, we are not able to deploy the agent: unable to generate policy XML for item

all the same "definitive" licence

Is it normal because of ended date maintenance period of the "licensing" ?

We know this Solution is out of support from Symantec, but we already use it without calling editor support from years...

Is it normal with definitive "license", we cannot deploy anymore ?

I believe NOT. Can you :

1. CONFIRM this is because of the end of the maintenance period license ?

2. Propose a valid WORKAROUND please ?
