Åben Dialog boks til import af txt filer

Vi kunne forsøge at gætte indholdet af LaunchCD, men hvorfor ikke poste koden?

Jeg er ikke super god til at forstå koderne, har får hjælp som nu 😊 så jeg ved ikke lige helt hvor jeg ska rette til 😬 ?

skal nok have rettet fil navne fra 32 bit til 64 bit men hvad skal de hedde ?

Du mangler nogle LongPtr og en LenB:
