Can't open 97-2003 Office docs in 2010

My company recently installed Windows 7 and Office 2010. Every time I try to open a excel file, via a link on our Intranet it asks for credentials.

I ruled out IE, firewall, and the document. I narrowed it down to something in Excel except i can't find it. Its like a security setting.

I was able to open the file when I had Office XP installed but as soon as i installed Office 2010 it won't work.

I've gone into the Trust Center and change settings but nothing seems to help. A pervious answer was given (http://www.sevenforums.com/microsoft...cs-2010-a.html) but it didn't work.

Any Ideas

Does this happen with just one specific Workbook?

To every workbook

No, this happens on every workbook. It even happens to Word documents, but not PDF's.

Since it worked perfectly before Office was installed and then perfectly with Office XP I think it's something to do with Office 2010.

I've changed every setting I can come up with and it doesn't work

Could it possibly be an installation issue?

Have you tried Repair or Uninstall, then Reinstall?

have u also tried saving a document in ur 2010 word into 97-2003 word format, and try to open that?
