When you double-click a Microsoft Excel file type (.xls), Excel starts as expected, but then you may receive an error message that is similar to the following:
When you click OK on the error message, the message reappears. After you repeatedly click OK, the file opens.
C:\filename.xls' could not be found. Check the spelling of the file name, and verify that the file location is correct. If you are trying to open the file from your list of most recently used files on the File menu, make sure that the file has not been renamed, moved, or deleted.
This behavior can occur if the Open action entry for this file type ends in %1.
If the Open action of the file type is edited and the line is restored before you press OK, a %1 is added to the registry key.
If you intentionally add a %1 to the Open action entry for this file type, a %1 is added to the registry key. If you subsequently delete the %1 from the Open action entry, the registry key remains unchanged and must be manually edited.
Additionally, this issue can occur when you manually change the file association of .xls files, or in some circumstances, when you are running multiple versions of Excel on the same computer.
