I am moving to a new computer with windows 7 from an older computer with windows XP. I have TMG v 6.12 on the old computer. I have made backup files of all my projects on the old computer so I can use them to "restore" to my new computer. But I need to know if TMG 6.12 is compatible with windows 7, or will I need to purchase TMG 7 for the new computer?
