Thank you for using Vertexshare Photo Stitcher Pro. After activating the Pro version, you will remove the 15 images limitation. It is a one-time fee and you can use it for a lifetime. Follow the next steps and you will learn how to activate the program with the received license key. The activating procedure for Mac and Win is the same.
#1 Click the “Upgrade” button and promote a new window where you can copy and paste your license key
#2 Click the “Upgrade” button and wait until the license key verification completes.
#3 Check the activating result and status.
Please note, you can use the delivered license key on both the Photo Stitcher for Mac and Photo Stitcher for Windows. But one key could be only used for once. If you want to use Photo Stitcher on multiple computers, you need to purchase more keys. If you want to transfer the key from the older computer to another new one, or if you have re-install your system, please send me an email and I can invalid the older one and generate a new key for you.
