Internal Software Error occured in CPP_API software. Requested Code -2147220693 Status Code: -224803

I have a small program that waits for a digital trigger and then reads from a channel. Using an NI-USB-6212. Everything works fine, except sometimes the program will fail to start. On debugging I see that the first line that interacts with the DAQ hangs. In this case it is 'DaqSystem.Local.GetPhysicalChannels(PhysicalChannelTypes.AI, PhysicalChannelAccess.External)'. Recently I was able to get the above error in Visual Studio. The only solution appears to be restarting the computer. This is obviously not ideal.  Any ideas?

Thanks,

-Matt

Hello Matt,

Please go ahead and download the following example from our website.

This example program shows you how to continuously acquire data (a waveform) using an internal clock and a digital start and reference trigger. 

Please use it as a reference.
