To upgrade from ePO 5.3, I have installed a fresh ePO 5.9.0 installation on a new Windows 2016 server and started migrating clients, policies, tasks etc. Everything works fine.
However, how do I go about updating to ePO 5.9.1? I downloaded the EPO591L zip and ran the setup, but the windows installer immediately fails with an error : "Error applying transforms. Verify that the specified transform paths are valid."
Am I using the wrong method to update ePO to 5.9.1?
