Could you help us understand better?
Where which version to which version are you upgrading ?
What is the upgrade path ?
I'm upgrading from VSE 8.8 Patch 4 to Patch 5.
I'm pretty noobish with managing VSE, and am doing so in ePO. I had attempted to upgrade the VSE on the OSS servers by just running a task to Install the newer version over the older one. What I found was that the self-protect feature of the software was blocking the upgrade. I tried turning it off, but that still didn't seem to work. The easiest path to get this working I found was to uninstall and reinstall VSE. But because I was worried about the dependencies between OSS and VSE I uninstalled OSS as well.
So my upgrade path was to uninstall OSS then VSE, then to install VSE and OSS.
Did we checked with the VSE team on why the upgrade was failing and who is blocking the upgrade ?
