Access privilege problem with Excel object

[Wellie]

I recently re-installed by windows XP and reinstalled Office 2003 with Word.
Now. when after inserting an Excel object and enter some data into embedded
Excel spreadsheet inside word and then exit to continue my word document.
Then, whe I try to double click the object to reactive the Excel, Word
prompted me a message stating that "Word cannot open the document; user does
not have access privileges."

I remove the Office and then re-installed it. The problem does not go away.

Can someone please tell me how to fix this problem ?
