Licensing Error in VeriStand API when Saving a System Definition File

Issue Details

I have a LabVIEW VI that uses the VeriStand API to read a System Definition file, make changes to it, and save the resulting file. The read portions of the code work as expected, but the write is never performed. I receive the following error:

42: License is not available or is not valid. NI  VeriStand must have a valid license


This is an issue with compatibility between NI VeriStand and NI License Manager. It was fixed in an update to NI License Manager. You can download NI License Manager 4.1 to resolve this error.
