Error -1073807346 VISA The given session or object reference is invalid

[jbrohan]

Hello
I'm using a DAQmxBase system with  a program based heavily on the interactive example for USB 800x. The program runs beautifully  in development mode, but fails when I run it after a build. The error has to do with the data acquisition. Is there some VISA module which needs to be added as a file in the Build process?
I am using version 3.2 of VISA and LBV 7.0

Thanks
John

Hello,

I suppose you already have a runtime engine on your PC, check if it have the different modules for VISA. If you create your runtime with your application install the VISA modules too, in Extra Installer tick the executable engine for VISA.

Hope this help you.

Thank you Rasheel
Now it works just fine. Just note that there are two similarly names VI's...make sure you get the right one!

Thans again
