I recently ran into the issue that users cannot open a file on the network as ‘read-only’ when one user already has the file open. Instead of receiving the option to open the file as ‘read-only’ they get the error: <filename> cannot be found. Check your spelling, or try a different path.

This problem seams to be specific to the user profile.

To fix this:

  1. Close Excel
  2. Open “RegEdit” from the command prompt from with in the users profile
  3. Backup the entire registry
  4. Now make these changes from within RegEidt:
    • Expand: HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\
    • Right click the “Excel” registry key and rename it to something like Excel-OLD
    • Exit “RegEdit”
  5. Open Excel. You will see “Windows Installer” popup and install something this first time you open Excel.
