My app works in the dev environment but not as an exe.

Hi nelg87,

Have you attempted to alter the IVI drivers to prevent it from closing the reference? Even if you can pass the reference, if it has been closed then you will receive errors when trying to call it. You might have to prevent the drivers from closing that reference.

Hi Mark,

Thanks for your response.  I can't modify the IVI driver because I don't have the source code.  I downloaded the driver from a vendor website so I don't have the .c file.  I did rewrite the driver using regular VISA commands and that solve my problem for now.  I still don't understand what I was missing to make my app work with the IVI driver and I will like to know because I'm sure I will run into this problem again.
