Yesterday one user reported that when he tried to edit a Microsoft Project document that is stored in a document library of a Microsoft Windows SharePoint Services Web site, he received the following error messages with Office (Project) 2003 installed on his computer.
‘Edit Document’ requires a Windows SharePoint Services-compatible application and Microsoft Internet Explorer 6.0 or greater.
I found a Microsoft Knowledge base article and did what it told me to do by updating the SharePoint support, but could not be successful. Then I tried the method 3 to register the Owssupp.dll but get the following error.
DllUnregisterServer in Owssupp.dll failed….return Error code 0x80070716.
I figured out the reason should be that the user installed Microsoft 2003 edition Office, and also some components from Microsoft Office 2007. Which somehow messed up the owssupp.dll register setup.
To resolve this issue, I had to un-install the Office 2003 SharePoint Support, and then re-install it. Here are steps I used:
- Click Start, and then click Control Panel.
- Click Add or Remove Programs.
- In the list of currently installed programs, click Microsoft Office 2003, and then click Change.
- Click Add or Remove Features, and then click Next.
- Click to select the Choose advanced customization of application check box, and then click Next.
- In the Choose update options for applications and tools box, expand Office Tools, click the down arrow next to Windows SharePoint Services Support, and then click Not Available.
- Click Update.
- After the update is done, repeat the steps from #1 to #5.
- In the Choose update options for applications and tools box, expand Office Tools, click the down arrow next to Windows SharePoint Services Support, and then click Run from My Computer.
- Click Update again.
Everything should be working now.
(please note: these steps above are only for Office 2003).
For Office 2007, you can try the same way but choose Office 2007 suite in the Add or Remove Program panel. Or try to do the following:
- Delete the owssupp.dll from C:\Program Files\Microsoft Office\Office12
- Run Microsoft Office Tool –> Microsoft Office Diagnostic
