When opening an Office file from a SharePoint 2013 site, you receive a message “The Webpage cannot be displayed” also in the address bar you will see the following:
Excel - ms-excel:ofv|u|https://abc.sharepoint.com/Shared Documents/Excelfile.xlsx
Word - ms-word:ofe|u|https://abc.sharepoint.com/Shared Documents/Wordfile.docx
This issue is seen when multiple versions of Office are installed on the same system and the SharePoint Foundation Support is enabled on both:
Office 2013 including products such as Lync, Project, Visio and Office 2010 or Office 2007
SOLUTION 1: (When Office 2007 is present)
NOTE: This solution doesn't apply to scenarios when the following 2013 applications are installed: SharePoint Designer, OneNote or InfoPath
To open the Office 2007 files in this scenario, go into the registry by typing regedit from the Run line and rename the SharePoint.OpenDocuments.5 key (ex. SharePoint.OpenDocuments.5.old) under HKEY_CLASSES_ROOT.
** This key will be added back to the registry anytime you run a Repair/Update of the Office 2013 program and will be have to renamed/deleted again.
SOLUTION 2: (When 2010 is present)
