�� Program �� folder is the default location where to install apps on Windows.
If a user does not have admin rights, he can simply install it under its home directory.
Users can choose to install Pharo Launcher where they wish.
We could choose another default location but not sure it is best option.
To me, the real problem is: why does Pharo apps (and Pharo Launcher) needs to write data in the application directory? By example, for Pharo Launcher, we do not need to load any code nor to backup sessions.
