Why do I get the error message "Project does not exist" when using the Copy Project command?

Description

The Copy Project command does not function correctly when a project is located in a directory that contains spaces in the name.

Make sure your project is located in a directory without any spaces in the name. You can rename the directory to use a symbol such as the underscore (_) as a place holder instead of spaces (For example, my_design).

This issue has been fixed beginning with the Quartus^® II software version 5.1.
