Like it says, the dongle option is NOT supported for Win 7 64-bit.
There are work-arounds, but they involve changing your license type.
Option 1: Switch to a CodeWarrior floating license.
Pro: Gives same flexibility as dongle.
Con: You have to set up a license server, which usually creates headaches for the IT people because they have to unblock a specific IP port.
Con: If you can't get a network connection, you can't use CodeWarrior.
Option 2: Buy a USB-to-Ethernet interface module, and tie the CodeWarrior license to its MAC.
Pro: Gives same flexibility as a dongle, and you get Ethernet connectivity in the bargain.
Pro: Proven to work, and does not require a network connection-- just plug the module into the USB port.
Con: Have to buy the interface module, unless you are using one already.
Hope this helps.
