The Annual License Fee Option gives you a license to use the FrameForge program for one calendar year from its installation, and you will always be eligible to get the very latest version of the software as long as your subscription is active. At the end of the license year, you will need to pay a new annual fee in order to continue using the program.
The One-Time Purchase Price Option gives you a non-expiring copy of the FrameForge program, including FREE upgrades for a period of a year. After that year, you can still use that edition of the software, but if we release a new upgrade which you want, you will have to pay a discounted upgrade fee.
