1. Open your Start menu and type Task Manager in the search field.

 

 

Select the Task Manager option from the menu.

 

 

 

2. The Task Manager will open, and you'll likely see a large number of instances of AutoCAD being open (32, to be exact).

 

 

Select each open instance and click End task.

click End task

 

 


3. Restart Windows.

 

 

Mac using Parallels?

 

Reset Windows by selecting Reset from the Actions menu.

Reset Windows

 

 

You should now be able to open AutoCAD or F/X CAD without getting the error.
