Hi alciati,
Did you install FM to a folder where you have write permission as a non-admin user? You can't install to the Program Files (x86) folder if you want to use portable/cloud mode. The simplest is to just re-install FM right over your old installation. Don't uninstall your old version. If you had portable/cloud mode on before, it would stay on, with all your same preferences. If you want to install to a new folder, or happened to uninstall first, you can turn back on the portable/cloud mode at: "Options / General Preferences... / Data / Portable/Cloud Mode". For more on setting up the portable/cloud mode, see these
instructions.
