We use Microsoft Office SharePoint Server 2007 for sharing and collaborating between
departments at work; it’s been working fine except when IE (both v6 and v7) would, most of the time, crash when opening a document, i.e., IE would just exits abnormally.
After some investigation, I found that the issue seems to happen when you have multiple versions of Office installed. At the moment, my machine still has some Office2k3 remnants, such as the Office11 folder under Program Files; however, I use Office2k7 full-time.
Anyway, here’s what you can do/try to resolve those crashes:
1. Go to C:\Program Files\Microsoft Office12.
2. Rename OWSSUPP.DLL to OWSSUPP.DLL.bak.
3. Run Microsoft Office Diagnostics, under Start > Microsoft Office > Microsoft Office Tools.
Hope this helps.
