Upgrading Endpoint Security using ERA ignores/resets settings and activation

[kapela86 10]

I used steps in this article https://support.eset.com.tr/kb3605/ to test upgrading one computer from 6.5 to latest 6.6 (without steps 13 & 14 as this is an existing install). I looked at that computer as it were performing an upgrade. First thing I noticed is that it reset all/some settings that were deployed to it using policies. For example I disabled "Show splash-screen at startup" but after upgrade it was re-enabled. Another thing was that ESET showed that it was not activated and I needed to provide our key to activate it.
