When you try to join external data to a Visio Maps layer, you may receive the following error message:
This error message can occur if:
- 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.
- 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.
- The DAO 3.0 drivers are not properly installed.
To reinstall DAO 3.0, download and run VMAPS10A.exe. The following file is available for download from the Microsoft Download Center:
