Hello! I'm using the program Revo Uninstaller and it found 3 versions of Joplin installed on my PC. Is that normal? Can I unisntall the older versions or will it create à bug? Thanks!
If we look at the sizes, obviously your joplin data directories (strange but maybe one for each installation I suppose) are not empty... So backup them (and more) before taking any action !
C:\Users\YOUR USER NAME\AppData\Roaming\Joplin
ETC...
