+23I am trying to install 2020.2 over 2020.1.3. Each time the installer fails with "FME Desktop 2020.2 Setup Wizard ended prematurely because of an error"
I have tried restarting the computer, tried on another day, downloading the installer again, for some reason it does not want to install on my machine.
Maybe I should wait for a new build.

The problem was that the uninstaller was searching for the old installer, couldn't find it but not asking for the path to it.
The uninstaller asked for the path but I didn't have the .msi file anymore and it wasn't on the downloads page .
I filed a problem to support, and they gave me the solution - C168635
They made the old installer file available. Updating still didn't work as it wasn't asking for the file, just throwing out a generic error but uninstalling (with browsing to the downloaded .msi for the old version) and installing separately worked great.
They also suggested I install the new version to a new directory but I don't need multiple versions.
So, thank you FME Support Team! You're great!
+26I had same error that drove me crazy for hours, and was down to the uninstaller refusing to remove the old version and so rolled back the installation after failing at this step. In my case the uninstaller can't handle User Folders on Windows like Documents being a redirected folder to a network folder share, and unfortnately the FME installer puts application data files in Documents.
Do you have any Folders like Documents not being actually in the standard C:\\ location?
+23The uninstaller does not start. The Uninstalling window flashes for a few seconds then the Error one appears.
I checked for relocated user folders, my user had only the OneDrive ones relocated so I unlinked and signed in again to OneDrive to reset them.
There was a user with relocated folders and I deleted the user altogether.
The error still persists. I think this is a bug not a feature
