Issue Details

I've added a simulated device to NI MAX (Measurement & Automation Explorer), but now I'm unable to delete it. What can I do?


This issue is caused to an internal error in NI MAX, to fix it please try to reset the NI MAX using the steps indicated in How to Fix or Reset the NI MAX Database File​​​​​​
If you are unable to access to NI MAX, please refer to the document How Can I Reset the MAX Database Without Opening NI MAX?
