SYMPTOMS

When you try to join external data to a Visio Maps layer, you may receive the following error message:

Error joining attributes from the
external file to the map layer

CAUSE

This error message can occur if:

1. You try to join an external data file to a map layer while the external data file is open in another application. Make sure the file is not open in another application before you try to join the data to a map layer.
2. The external data file you are trying to join is a Microsoft Excel 97 file. Data Access Objects (DAO) 3.0 does not contain a driver for Excel 97. Therefore, you must save your Excel 97 data files to an older version of Excel before you try to join the data to a map layer. When you save to an older version of Excel, make sure to use a new file name to prevent data loss.
3. The DAO 3.0 drivers are not properly installed.

RESOLUTION

To reinstall DAO 3.0, download and run VMAPS10A.exe. The following file is available for download from the Microsoft Download Center:
