OK, thank you. Would your engineer know if the FTD2XX.DLL installed as part of Adept where i can leave the Adept API calls in the code I have and only access FTD2XX.DLL to program MPSEE when needed, or is this an "either/or" situation where I have to install FTDI support seperately and remove Adept? or can both co-exist? does Adept use the FT2XX.DLL so it is already present, and its just a matter of accessing that lower level driver directly when needed, circumventing the API for just one function (MPSEE).
