OLE Registration Error Occurred

I am using Windows XP SP3 with MS Office 2003. Mostly I work with Outlook and use Word as the editor for same. Since yesterday whenever I open Outlook and try editing, it says word is no available, sometimes it says not installed or not from the same version as outlook. After trying a lot I though re-installing MS Word may fix the problem but after removing word it wont allow me to install it again. I even trying re-installing complete Office suite but dint helped.

Any suggestions please?

I think you need to re-register the object. It may fix the problem. Just go to Start, click RUN. Type the following and press Enter:

"regsvr32.exe ole32.dll"

This will reregister the object must fix the problem.

Thank you very much for the help karma. That really helped me to get rid of the same.

Appreciated.
