If you, from SharePoint search, try to open a document and at the end get to a page looking similar to below URLs:
- ms-owerpoint:ofv|u|http://www.examplesite.com/Shared%20Documents/Presentation1.pptx
- ms-word:ofv|u|http://www.examplesite.com/Shared%20Documents/Test.docx
- ms-excel:ofv|u|http://www.examplesite.com/Shared%20Documents/songs.xls
It is likely that it is due to mixed versions of different Office application in the client machine.See this blog article for information about how to resolve this issue:http://sharepoint.stackexchange.com/questions/88530/office-files-wont-open-in-sharepoint-2013
