I was incidentally trying to install a QGIS Standalone Installer Version 3.6 (64 bit) on a 32 bit Win OS, which seemed to work, but gave a restart of the system at the end and left the start menu only with Grass Shortcuts. Starting C:\Program Files\QGIS 3.6\bin\qgis-bin-g7.exe manually finally gave the message that explained everything: wrong OS. It would be perfect if that bit of code could be copied to the install routine, thus preventing user misbehaviour ;-)
Thank you in advance, it's great to watch QGIS growing and getting better all the time!
