The application was unable to start correctly (0xc000007b)


To start, I would suggest to test whether there is a problem between your application and its dependencies using dependency walker


A load time dependency could not be resolved. The easiest way to debug this is to use Dependency Walker. Use the Profile option to get diagnostics output of the load process. This will identify the point of failure and should guide you to a solution.

The most common cause of this error is trying to load a 64 bit DLL into a 32 bit process, or vice versa.


It is a missing dll.Possibly, your dll that works with com ports have an unresolved dll dependence. You can use dependency walker and windows debugger. Check all of the mfc library, for example. Also, you can use nrCommlib - it is great components to work with com ports.
