IE / SharePoint crashes when opening files from hyperlinks

This error occurs when there is a mixed Office 2003/2007 enviroment on a PC. I.e. Office 2003 is installed then Visio 2007 is added later.

To resolve this you need to browse to C:\Program Files\Microsoft Office\Office12\

and delete OWSSUPP.DLL

After this run the Microsoft Office Diagnostics from;

Start > All Programs > Microsoft Office > Office Tools.

This will repair and register the .dll


In Lieu of this a work around is to right click the hyperlink and chose "open in a new window"
