Hi !
If you installed Office, then you will be having
PowerPoint and Ms-Access, unless you have done a Custom
installation.
Please, check by clicking on the Start button and going
to Programs option. If you can't see an option for
PowerPoint or Access, then click on the option called
Office 2000.
OR
CLick on the Start button, click on the Run option.
type "powerpnt" (without the quotes) in the box displayed
and click on the OK button.
If none of this work, you need to install afresh.
regards,
kiran
