When running my FT4222H application program, I see the error “LibFT4222.dll is missing from your computer”. How can this be resolved?

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.
