How do I configure BitDefender with Connectify?

In the BitDefender Firewall settings, there is an option called "Block Internet Connection Sharing." Disable the Block Internet Connection Sharing option, then in Connectify Hotspot click Stop hotspot and then Start hotspot.

If BitDefender stops Connectify Hotspot from working at all, clicking Start hotspot may show this error instead:

Connectify is not able to function correctly, because another piece of software is blocking Connectify. It is most likely a third party security software. Please remove the software, or have it unblock Connectify to continue.

The name and place of the option may differ in your version of BitDefender. For the programs and ports to allow, see How do I configure my firewall to work with Connectify Hotspot?
