O&O DiskImage automatically checks if your program version is a current one or if a newer version is available.
Under Help/About O&O DiskImage you can see your license data and the number of your program version.
So-called "Minor Updates" (Version 14.0 to 14.1, 14.2, etc.), where smaller changes in the program have been made, are free. "Major-Updates", such as from version 13 to 14, must generally be purchased.
If you are using O&O DiskImage from a network and performing a major update, you will need to copy the password file if you want to use the automatic authentication. After a full installation and the restart, you will need to place the password file in the O&O DiskImage default folder. After restarting, the password management has to be started and the password has to be entered for the password file. As a result, the required initializations will be run and automatic authentication can continue to be possible.
