SYMPTOMS

When you start Microsoft Project for the Macintosh, you receive the following error message:
The application Microsoft Project could not be opened because MicrosoftVisualBasicAppsLib could not be found

CAUSE

This issue can occur if either of the following conditions is true:
  • An extension is either missing or disabled, or it is the incorrect version.
  • Virtual memory is turned off.
If Microsoft Office 98 or Microsoft Office 2001 for Macintosh is installed, the wrong version of Microsoft Visual Basic for Applications may be in the extensions folder. Microsoft Project for Macintosh requires Visual Basic for Applications version 1.0.1, Microsoft Office 98 uses Visual Basic for Applications version 8.0, and Microsoft Office 2001 uses Visual Basic for Applications version 9.0. The Microsoft Office versions do not require that their version of the Visual Basic for Applications extension be in the extensions folder.

RESOLUTION

To resolve this issue, use the appropriate method.

Method 1 - Turn Virtual Memory On

Confirm that virtual memory is on. To do this, follow these steps:
  1. On the Apple menu, point to Control Panels, and then click Memory.
  2. Confirm that virtual memory is on.

    Note: After you make changes to virtual memory settings, you must restart the computer for the changes to take effect.

Method 2 - Confirm That the Correct Version of VBA Is in the Extensions Folder

  1. Open the Extensions folder in the System Folder.
  2. Attempt to locate the following extension:
    Visual Basic for Applications
  3. If you do not find the extension, reinstall Microsoft Project.

    NOTE: If you are using Mac OS 9.1 or later, use the information in the following article to reinstall Microsoft Project:

  4. If you do find the extension, click the extension, point to Get Info on the File menu, and then click General Information.
  5. Note the version of the extension. If the version is not 1.0.1, do one of the following:
    • If the version of the Visual Basic for Applications extension is 9.0, move the extension into the Office folder inside the Microsoft Office 2001 folder.
    • If the version of the Visual Basic for Applications extension is 8.0, move the extension into the Office folder inside the Microsoft Office 98 folder.
  6. On the Apple menu, point to Control Panels, and then click Extensions Manager.
  7. Turn off the Extensions (click to clear the Extensions check box).
  8. Restart the computer, and hold down the APPLE + OPTION keys while restarting. This rebuilds the Desktop. Click OK to confirm that you want to rebuild the desktop.
  9. Reinstall Microsoft Project 4.0. This places the correct version of the VBA extension in the Extensions folder in the System Folder.
  10. When Setup is complete for Microsoft Project 4.0, restart the computer.
  11. On the Apple menu, point to Control Panels, and then click Extensions Manager.
  12. Turn on the Extensions (click to select the Extensions check box), and then click Restart.
  13. After your computer has restarted, start Microsoft Project.
