Buying and Activating a ReefMaster License

Click Activate License, either in the start-up window, or in the About ReefMaster window, which can be opened by clicking the About menu option in the File menu.

Other Activation Options

Other options are available in the License Activation window, including offline activation and extending the ReefMaster trial period. To see these options, click the Other Options toggle button.

Installing additional ReefMaster modules

Volumes and Areas, Bottom Composition and Sidescan Mosaic are additional ReefMaster modules that can be activated by following the upgrade process from the ReefMaster About window. Note that these are additional-cost modules, and that the upgrade process may involve visiting the purchase website.





Open the About ReefMaster window by clicking on the About ReefMaster button at the top of the Main Toolbar.

The installed status of the Bottom Composition, Volumes and Areas and Sidescan Mosaic modules is displayed.

To add a module, click the Upgrade button.

The Upgrade License window is shown:



Adding a module by purchasing from the ReefMaster website


Click the Upgrade button (1) next to the text "Purchase an upgrade online:".

This will open the default web-browser to the module purchase page, and include details of your current license key, which are required for the upgrade process.

Follow the purchase process.

Once the purchase is completed, return to ReefMaster and click the Reactivate License button. This will update your current installation, and the installed status of the purchased module should change within the About window.

Restart ReefMaster for the changes to take effect.

If the same ReefMaster key is also being used on another PC, then the licence must be reactivated on that machine by clicking the Reactivate button, before the new features become available.


Adding a module using a pre-purchased license code

Modules can also be added by using a upgrade code purchased from a ReefMaster reseller. If you have a pre-purchased upgrade code:


Enter the upgrade code into the space provided (2). Upgrade codes consist of a sequence of letters and numbers, and are not case sensitive. It is important that the code is entered correctly.

Click the Upgrade button (3).

ReefMaster will contact the license server and attempt to install the module upgrade. All of the modules associated  with the specified upgrade key will be activated.

If the same key is in use on another PC, then the license on that machine needs to be reactivated before the new modules become available (note that the full upgrade process does not need to be performed again on the second machine, and would actually fail because the upgrade code has already been used). To reactivate the license on the second machine, open the About window and click the Reactivate License button.


Deactivating a ReefMaster License

Licenses can be deactivated so that they can be re-activated on a different PC.


Open the About ReefMaster window by clicking the About ReefMaster option in the File menu.

Click the Deactivate License button.


Uninstalling ReefMaster

To uninstall ReefMaster, use the Windows function Control Panel/Programs/Uninstall a program.
