Why has am I prompted to (re)install Microsoft Office every time I try to use Excel?

Question

This has happened before, completely out of the blue. One minute Excel works fine, the next it prompts me to reinstall Office even though Word is functioning perfectly. Last time it just went away on its own after about a week. It hasn't been that long yet, but I'm wondering if there's anything I can do to circumvent the problem.

Answer 1

I know a certain situation where it may happen to any MS Office application in WindowsXP environment. (Not specific to MS Excel).

When you try to open an Office document such as 'Excel spreadsheet' from Windows (i.e. by double clicking the icon...) a dialog box with a progress indicator may appear showing like that the corresponding Office application is being installed. The progress indicator freezes in half the way. Nothing happens if you hit 'Cancel'. The only way to open a document is by first starting the application manually and then opening the document inside from the application.

Solution:
Temporarily make the user account an 'Administrator'. Next time when the progress bar appears, let it go all the way. If it asks for the 'Original Office Installation CD' or the folder, which contains the 'installation files', provide those. You are successful if the dialog box disappears after the progress bar reaching 100%.

After that you can remove 'Admin' privileges if you need and make the account as it originally was. Now it will work fine.

I opened the powerpoint with 2007, and all the face backgrounds and pictures weren't there.
