Daqmx C-API 64-Bit Version



I'm struggeling with a older Excel VBA application which is supposed to run on a new LapTop. Unfortunately this Laptop comes with a 64-Bit Office. Now DAQmxRegisterEveryNSamplesEvent is causing an type mismatch for the parameter of the callback handler. I think this comes because a 32-Bit address is expected by the fuction.


Is there a 64-Bit Version of the C-API or an other solution.


With kind regards,

DAQmx is certainly as 64-bit version available. Which DLLs do you try to load, from which path?
