Operating System: Windows 11

Hello,
I have a problem with OriginPro 2018 related to nonlinear fitting. After selecting the graph, I follow the path:
Analysis → Fitting → Nonlinear Curve Fit...
The NLFit window opens, but I can't access the various functionalities—for example, I’m unable to define or select functions. It seems like the interface is either incomplete or not responsive.


Has anyone encountered a similar issue or knows how to solve it?

Thanks in advance!
