Windows installation notes

    In Windows 7 and later FreeShip can be installed per-Machine or per-User. Per-Machine is default and is more secure in general, because per-User files will be installed into user profile and are vulnerable to modifications thet can be done by malware. Per-User installation does not require escalation to "Run as Administrator".
    The installation MSI file is currently capable for install/uninstall only, no updates/patches. You will have to uninstall current version to install new version.
    Backup your projects, models, exports, imports ... etc, just in case.
    Backup and remove FreeShip.ini files because file layout is changed. See below.
