Could you please specify the version of the agent currently installed and which version you want to install or upgrade??
The ePO is version 5.3 and the agent on the machines in question is 5700.7163. I am trying to push 5800.7501
You can try append the update task to include the engine 5800 version. Are those endpoints , up to dat in terms of dats ? youcan redeploy the agent with the force install option, and see it that helps with the engine upgrade.
Not all are updated with the current .dat files. That is another item of issue. I have done a "Wake up Agents", Update Now and Deploy Agent as well as using the "force install" option. I have no idea why these machines will not receive the new engine or even .dats on some ....
This is becoming increasingly frustrating and I am wondering if I need to manually uninstall and then attempt to reinstall.
