This error is a known bug in Connectify 3.1. It is completely fixed in the latest version of Connectify.

This crash is caused by a corrupted download of a Connectify driver file. Typically the download is corrupted by a "Captive Portal" Internet source found in hotels and coffee shops.  Any time you're required to enter information at a hotspot before connecting to the Internet (which is the case for most open hotspots), you are on one of these captive portals.

If for some reason you don't want to update to Connectify 3.2, we have a workaround to get you up and running. This problem, however, can reoccur after using a captive portal again.

1.) Delete driver.dat in C:\ProgramData\Connectify\cache
2.) Test Internet connection, browse the Internet, make sure you are not being redirected (captive portal)
3.) Restart Connectify Hotspot
