This can happen if the LibFT4222.dll is not found by the program.
Simply copy the LibFT4222.dll into the same directory as the .exe, or copy the LibFT4222.dll into the C:\Windows\System32 directory.
Now it should run.
You can modify the projects or create your own project. These are only examples which we provide.
Note: This also applies to other projects that use a DLL, not just LibFT4222.dll.
