Read Only MOSS 2007 and Office 2003
There are quite a few people who’ve pounded their heads against a wall trying to open documents in a MOSS environment, only to find they default to read-only. This is despite either clicking on the document, or selecting the ‘Edit in Microsoft…’ menu item. When you go to save the document, it prompts that it has been opened as read only and cannot be saved.
I tried some of the below search strings without much luck:
Edit Document requires a Windows SharePOint Services-compatible applicaiton and Microsoft Internet Explorer 6.0 or greater
Dllregisterserver in owssupp.dll failed. Return code was: 0×80070716
Solution:
Despite some posts hanging around stating there is none, this has worked for me. Rename the following file (whichever version of office you have between xp and 2007) and run a repair on the Office installation (You do have the Sharepoint Services Support tools installed, right?)
For me this file was in: C:\Program Files\Microsoft Office\OFFICE11\OWSSUPP.DLL
Restart your browser, and now the appropriate office app will fire up in a new window (as opposed to the seamless ‘read-only’ view) for editing!
