I am suffering a common problem still, despite uninstalling Project 2003 previously to try to fix a dll clash.
My system was working fine. I could open and edit documents from SharePoint just fine. Something broke it - and I believe (as in the article at the start) that that was Windows Update.
Now when I try and edit a document, I get the error
‘Edit Document’ requires a Windows SharePoint Services-compatible application and Microsoft Internet Explorer 6.0 or greater.
Which is annoying, as I have this. I looked up the knowledgebase article, followed the instructions, and ended up trying to register/unregister the dll. Except that I can’t. When I try, and I get the error
The module “owssupp.dll” was loaded but the call to DllUnregisterServer failed with error code 0×80070716.
Apparently
This exit code means that “the resource name specified cannot be found in the image file”.
Ooookaaay. Risking my geek credentials, that is gibberish to me. Uninstalling and reinstalling SharePoint Support in the Office features did not fix the problem for me.I think I’m looking at a full Office reinstall. What a load…
