SUMMARY
If the Microsoft Excel Setup program is launched while Excel is running in the background, error -49, &quot;File System Error, Unable to continue operation&quot; may appear. After you click OK to close the alert box, another alert states &quot;Install Interrupted. Some Options May Be Only Partially Installed,&quot; and the Setup program returns to the initial Setup screen.

This error occurs because the Setup program is trying to write information to the &quot;Excel Settings&quot; file, which is already in use by the other copy of Excel.

For best results with Setup, quit all copies of Excel before running the Setup program.
