What to do – to legally use no longer sold PhotoDraw2000 Ver2

At our company I have one license and the media for Office 2000 Premium. Ofc2k Prem includes Photodraw 2000. The sale of Photodraw was discontinued in 2001. I like the product & it can adequately serve the needs of users at our company.

Licenses for Office 2000 Premium no longer can be purchased. I want to be compliant, but is it really necessary to purchase a license for a more current version of MS Office to legally utilize Photodraw?
