I've tried SO many different ways to get to this to work for hours, keep getting the same error. HncAppShield.exe is compiled with VC++

This error usually means that the coverage map is empty, usually because either -coverage_module is incorrect or the module specified (AppShieldDLL.dll in your case) isn't reached during sample processing.

I would go back to the debug mode, check that there is AppShieldDLL.dll in the log, check if the coverage map in the log is empty and also check if that module is used for sample processing. If AppShieldDLL.dll is used for processing of some samples, but not all of them, then another -coverage_module should be added that is used for all samples (HncAppShield.exe?)
