By purchasing the product you purchase the License which can be activated on up to 3 different machines at the same time.
If you activate the license on the same machine for the second time it’s still considered as one activation. When you format your disk and install the product again you might increase your current activations. If you happen to run out of activations (new PC, hardware change, etc) – any old activation can be removed.
When you need to reset your activations you can request a license reset using the my license page.
