I don`t know why the installer doens`t show up, but running the setup file still installs the application as far as i can see (in ~/drive_c/users/louis/Local Settings/Application Data/Opera Software/Opera Neon/Application)
Did a retest with wine 3.20 and it is just like you said. Bug can be closed.
