While we're confident that the update has been tested thoroughly and is safe, it's always a good practice to compact and back up your trees periodically, and we strongly recommend it before an update. Note that the update will not change any of your settings and preferences - those are preserved and will automatically continue post-update. If you need a replacement download, click here for instructions on how to pick up your copy. If you need to reinstall FTM 2017, please refer to the email you received after purchasing for download links, or to the downloaded installer file if you saved it.
Because this is an updater and not a full installer, make sure that FTM 2017 (either version 23.0 - build 343, version 23.1 - build 480, or version 23.2 - build 540) is installed before running the updater.
