I have JOSM 17919 on my computer. Downloading the 18193 setup.exe and installing it leads to only opening the old 17919 version.

Closed as duplicate of #21307.
There is a problem with updating from java 8. Please, uninstall JOSM and likely java 8 (which is a 32-bit version anyway) and then install the new JOSM installer.
