When you try to save your Microsoft Project 2000 file, you may receive the following error message:
The file cannot be opened.

Check that the file name and path are correct
Check that the file format is recognized by Microsoft Project

Microsoft Project files saved in a version earlier than Microsoft Project 98 can't be opened.

If your file is from an earlier version, open it in that version, click Save as (File menu), and save in MPX format. Open the MPX file in the current version of Microsoft Project. When you use this method, project data is imported, but formatting is lost.


This issue occurs under the following scenario:
  • You open a Microsoft Project 2000 file in Microsoft Project 2002.

  • You run a macro and then save the file.

  • You start the Microsoft Visual Basic Editor to edit or create a new macro, and then you save the file.
The file saves with no errors. However, when you try to save the project file a second time, you receive the error message described in the "Symptoms" section.
