Renewing an FX MathPack or FX SciencePack subscription does not need to create a large workload for system administrators.

You do not have to download and install new versions - but we recommend that you do. Resubscription is a great time to make sure that you are using the latest versions of the products. If you choose to not update your copies when resubscribing, we recommend that you schedule some other convenient time to do so.

You will need to resubscribe one computer before resubscribing all computers on your network. There are a few ways of entering your new subscription information.

If you have downloaded a new copy of FX MathPack or FX SciencePack, you will be asked for subscription information during installation.

Alternatively, you can choose Register from the Help menu of any of the products included in the pack. You only need to enter your new subscription information into one of the products - the information will automatically be available for other products in the pack.

Your subscription information will be written to a file in the Efofex Program Files directory on your computer. This file will normally be

C:\Program Files\Efofex\FXMathsSub.ini

or

C:\Program Files\Efofex\FXScienceSub.ini

You can resubscribe any other computer by copying the FXMathsSub.ini or FXScienceSub.ini file to the Efofex Program Files directory on the new computer. No other action is required.

If FX MathPack / FX SciencePack are run from a network share, computers do not need to be individually registered.
