Compilation Error In Tia Portal

I am working my way through the TIA Portal HMI Course. I got to a certain point, but now when I go to simulate the HMI, I get an error.
Error

Please help me resolve this error.

The error is
Internal ERROR (detail inconsistent compiler data, please perform Software “rebuild all” on the project)
Error_2

Hello there! I’d be glad to help you!

  • Can you please share more details about your configuration and what are you attempting to do ? Like some screens ?
  • Also, have you tried to rebuild the HMI application ? I joined a screenshot to show you how it’s done.
    Rebuild HMI

Regards.

Redouane,
I just performed the software rebuild all and now the HMI is working and I am able to compile without errors.

I am at the point of the course where the HMI screen buttons (Start/Stop) are added. After I added these buttons is when I got the error. However, it seems to be resolved now after you showed where to do the full software rebuild.

Thanks
