How do you silently upgrade PsychoPy from 2.2 or 2.4 to 2.5?
If I just run:
start /wait StandalonePsychoPy-2022.2.5-win64.exe /S
It exits with error -1073741819
If I don’t do it silently, it gives me an option to uninstall the old version.
To me the ideal is to make the installer an msi. Since the nsis uninstaller runs “un_a.exe” in the background, problems happen.
