Easy Transfer will not help you, unfortunately. From its download page: "Windows Easy Transfer does not migrate installed applications." If the app cannot be installed in Win7, it won't run in it either.
If you don't want to buy the upgraded versions and the ones you have won't work, I don't think there's anything more I can suggest. To find out if it will run in Win7, you can: 1) Try it yourself, or 2) check the Windows 7 compatibility site
. You can search there for software and hardware, and it can tell you if it is compatible.
Let me know how it goes, and if you decide to try it yourself I can tell you how to install in compatibility mode.
