Office not running for a specific user

[Stryker]

Hi,

When a user runs office 2003 on his machine he gets the error:

"The operating system is not presently configured to run this application"

However, when I login as another user, it works fine.

The user in question is a local admin. I have tried uninstalling and
re-installing office, but this has not worked.

Please help.

Thanks

Dil
