When downloading a new version of Pharo Launcher in windows, it requires to uninstall and reinstall the application. We should have a better way of performing the update.
it only happens for "dev" version.
dev versions are numbered 0.0.0.
So, if you already have a Pharo Launcher stable version installed, it is not seen as an upgrade.
I do not have a better solution for now.
