Functionality is Locked Until Land F/X is Loaded



You received the following error message:

Land F/X Not Loaded: Functionality is locked until Land F/X is loaded




This issue can occur because:

  • The Land F/X menu may not be loaded.
  • The file landfx.vlx may have been unable to load.
  • License validation my have failed.

Did you receive this error when attempting to plot to PDF?

If so, you might be experiencing an issue with the Background Plotting or Background Publishing setting in CAD.



You will only see this error message if you have F/X CAD 2014. We've since replaced it with the message F/X CAD cannot function without Land F/X installed correctly.


For causes and solutions, see our F/X CAD cannot function article.
