Hi Mark,I recently set up Myriad 3.6 on a 64 bit system which worked very well everything that is except the Advantech 1750 card which even though Advantech have produced 64 bit drivers the front end of Myriad refuses to see them saying asapi 32.dll file is missing. This is really annoying as the 64 bit os is much more stable . Just wondered if you have worked around this issue somehow. Thanks. David.
