Created attachment 37881 [details] msi: Format the value name from the reglocator table.
This should help.
Yes, it definitely helps. Another problem surfaced: after I clicked on Yes button, it waited for a bit (half minute) then proceeded correctly. Attaching log for you to see, reproduced every time.
Yes, that's when it runs the uninstaller. It's started in quiet mode so you get no feedback. Interestingly it shows a UI on Windows despite being started in quiet mode, so it looks like the parent installer mode has precedence, or something like that.
