I have configured a TCP/IP instrument in NI Measurement and Automation Explorer (MAX), which is working correctly. I can open a VISA Test Panel and I see it in the Network Resources tab as connected. Nevertheless, if I close NI MAX and open it again, the instrument shows up as disconnected (gray with a red "X" icon). I can validate the connection and see the Web Page, but NI MAX will not let me open a VISA Test Panel. Why does this happen and how can I fix it?
Try the following steps until you see your instrument connect successfully after closing NI MAX and opening it again:
This error can happen because of the visa32.dll being corrupted or not installed by National Instruments. It can be seen when the computer has installed VISA software from third-party vendors.
Thank you for your feedback.
