Error -200088 with PXIe-6341 when trying to create AI channel

[db314159]

I'm getting an Invalid Task error (-200088) when trying to create an AI voltage channel on a PXIe-6341 card. I've attached a sample Python script which triggers the error. I checked NI-MAX and the test panel there can read the voltage I'm trying to read. The script has previously been running correctly, but has started triggering this error recently. I suspected a driver issue, as we recently upgraded the computer it's on to Windows 10, but reinstalling the drivers and NI-DAQmx had no effect. Anyone have any suggestions for what may be causing this error?

Figured it out... Turns out that the new version of DAQmx returns the task handle as a 64-bit integer rather than 32-bit, so the solution is simply to change the data type of the task handle variable to 64-bit.
