I uninstalled openconnect-gui, leaving just the TAP adapter installed and whatever Visual C it installed B4. I also deleted the C:\Program Files (x86)\openconnect folder. I copied your 2 new modules into the "test" folder with your other "test" modules, overlaying those 2. I reran and did notice a few warnings about "signer not found", but it continued right to the same spot and died.

I've updated http://david.woodhou.se/openconnect.exe and http://david.woodhou.se/libopenconnect-5.dll so we should get a clearer picture of how far it gets. Please try with those. -- dwmw2
