I have been updating our servers and found several issues with the provided patchnotification tool.
ArcGIS Server 10.7 (not .1) on Windows:
The tool suggests a patch that is only available for Server 10.7.1, downloads it, and then fails to install.
"ArcGIS (Desktop, Engine, Server) File Geodatabase SQL Performance Patch" https://support.esri.com/de/download/7863
ArcGIS GeoEvent 10.7.1 on Windows:
The tool downloads "ArcGIS GeoEvent Server 10.7.1 Patch 1" every time I run it, even though it already successfully installed it. I also tried installing this patch manually between runs, which does not change the behaviour. There is a newer patch "ArcGIS GeoEvent Server 10.7.1 Patch 2" (aka. "ArcGIS GeoEvent Server Security Update 2021 Patch") which should include patch 1 (cummulative update), the tool lists this one as installed. I'm not sure if the tool gets confused and thinks Patch 1 is not installed when Patch 2 is?
Worst of all, due to a long-standing bug the tool quits after every installation and there's no way to simply download all patches. Are there plans to backport the fix? Can I use the fixed version from 10.8.1 on an older installation?
