There is now a single installation file for both Professional and Home licenses. After you install the program and input the registration key, The Bat! will recognize its license type.

Please check your current registration. You may have to pay to upgrade your license to a newer version. Licenses purchased on or after May 9, 2015 are valid for The Bat! v7. Licenses purchased on or before May 8, 2015 can be upgraded for a fee.
