Hi,
Microsoft no longer provides a way to download it since it was discontinued years ago. If you still have the original CD installer, you can try installing it on your new computer, but I doubt it will work smoothly due to compatibility issues with newer systems.
If you want an alternative, you can try these apps and see what works for you.
