Thank you for looking at this. I removed the condition for RemoveExistingProducts as you suggested. I didn't want to have any complicated behaviour. It didn't help however, as you guessed.
I have tried the MajorUpgrade too but it doesn't work as I want neither. As far as I can tell it works just as bad as the <Upgrade> and <RemoveExistingProducts>. Your idea about adding perMachine is interesting. I tried that. Do you have a tip how I can block upgrade from older versions and tell users to uninstall first? I can certainly show the installation log. How should I do it? Post the whole log inline in a email to wix-users? I have a question about file versions. If file versions are not set, could that cause my old files to be kept instead of replaced when I install a newer version? When I rightclick on my exe and select properties it says that the productversion is 1.55 (which looks good to me) but the fileversion is 0.0.0.0.
