Issue Details

I am trying to deploy shared variables to my Real-Time target and I get error message Error -1967357949 occurred at an unidentified location. Possible reason(s): Unable to query Measurement & Automation Explorer.  What can I do to fix it?


The solution is to install the Network Variable Engine software on your Real-Time target. In order to check whether or not this software is installed, expand the Software tree on your device in  Measurement & Automation Explorer.

If installed you should see Network Variable Engine as seen above.  This is the engine that is referred to as the Shared Variable Engine in the error message.

If the engine is not present and you need to install it, follow these steps:
     1) Right-click on Software and select Add/Remove Software.
     2) Select the LabVIEW Real-Time Software and then select Next.

3) Check the box next to Network Variable Engine and select Next.
4) Select Next again to review the configuration and the software will be loaded onto the Real-Time target.
The Network Variable Engine is now installed and the error should not persist.
