Cause

Visio cannot open or edit a file associated with files being published. This may be caused by a window, e.g. the Properties Window, being open when the file is being saved or a file being open for editing.

Solutions

• Check the file listed for open windows
1. Open the associated Visio file. (It should have the same file name as the HTML file cited in the error message, but will be stored in a different location.)
2. From Visio's View tab, click Switch Windows.



Switch Window dialog
3. Is there more than one window listed? If so, select any such windows to bring them to the fore, and close them. The only window that should be listed is the main drawing window ('Drawing1' in the above examples).
4. Save and close the file.
5. The file should now publish, assuming no other problems.
• If the above did not solve the problem, you will need to check that all the other Visio files linked on the map can be edited by Visio. These should include any files drilled down from activities, files on the Off-page Connectors and the file on the Hyperlink circle (bottom left).
1. For each file, attempt to open it in Visio. You may find that you get an error message that the file is already open for editing, in which case you need request the person to close the file.
2. When are files are closed, the file should now publish.
