Hi,
mesa.dll is a module used for user interface components and should have been installed by the CVI run-time engine.
the dll should be at C:\Program Files\National Instruments\Shared\Mesa. Make sure that you have the dll in the system. I would suggest that you uninstall the run-time enigine, delete this folder and reinstall the run-time engine. Then you can check whether this component was intalled or not.
I hope this helps.
