This error occurs for the following reasons:
- New Project Wizard (NPW) is used to create the new project (as opposed to New Project Dialog). NPW is the default.
- The project Type selected is EDIF.
- Both the EDIF file and the associated UCF file are added in the New Project Wizard.
- The "Open Design Summary when project is opened" option is selected. This option is on by default.
You can prevent the error by changing any one of these conditions.
