This error is the result of a missing license file on the host system when trying to run the (legacy) VideoMASTER software.
When you purchase a VideoMASTER hardware and software package, National Instruments sends one or more license files to you directly via email. Each license file is associated with a corresponding piece of NI hardware. This association is indicated by the name of the
file, which includes the hardware serial number as part of the name.
These license files should be copied to the
C:\Program Files\microLEX Systems\License Files
folder on the host computer after installing the software. If these license files are not present, you will get the error above and will not be able to run the VideoMASTER software.
If you have a license file in the correct location, make sure the serial number indicated by the file name matches the hardware you are using on the system. Make sure the license file is not an evaluation license that has expired.
If you did not receive the appropriate license file via email or need to recover a lost license file, you can email the serial number of your NI hardware to email@example.com
to request a new license file.
