To keep your MasterScanner up-to-date, we suggest to install the IAC's Linux Mint additions and the latest software version.
1] Determine which Linux Mint version your MasterScanner is running on. See the wallpaper on the desktop or via the Tools menu.
2] Download + install IAC's Linux Mint updates (Mint 18 + 19 only).
3] Create a backup of the MasterScanner's settings via the Tools menu option.
4] Download + install the latest MasterScanner software.
5] Request a new Activation Key, via submitting a ticket in the Support Center.
The latest Linux Mint updates and the MasterScanner software can be found at the following locations:
Note 1]: The support for Mint 17 has ended, the version 3.15.14 is the last version for Mint 17.
Note 2]: For a new Activation Key we need the Project Nr / Machine Nr, and the Activation ID.
