Issue Details

When I try to run the VI with Math Script Node, LabVIEW displays below error:

Error 1046 occurred at an undified location

Possible reasons(s):

LabVIEW: LabVIEW cannot initialize the script server. Ensure the server software is installed in concerned VI.


Following the instructions of the error source, when I tried to reinstall LabVIEW Math Script 2015 (as per  my LabVIEW 2015 version), installation failed with the message: no software will be installed or removed

What can be the cause of Math Script Node failure in my LabVIEW VI?


The above error can arise because of two reasons:

1. Math Script RT Module is not installed properly. 
2. Math Script RT Module is not licensed.

As obvious from above re-installation steps, the Math Script RT Module is installed correctly for the current LabVIEW version. However, Math Script RT Module was not licensed (license was expired for the version of Math Script RT Module).

Issue was solved by licensing the Math Script RT Module.
