I tried reinstall the MathCAD and it works, it's OK. but if we can find a quick way such as "a registry value" or "a setup method", it will be better when we meet this problem next time. I tired to use the Microsoft(R) Registry monitor to find what Registry keys and value the Creo Parametric read and write when i run the insert MathCAD table files, but it doesn't work, i sitll not find the way.
