I need to download Office Professional Plus 2010, and I can't seem to find it anywhere! I have the product key, but my laptop does not have a disk drive.

Hi,

this article may help:

Depending on the method you used, to acquire Office ProPlus, you may need to re-visit that channel,
e.g. if you purchased retail, the article above should help.

if you purchased via HomeUseProgram (HUP), an employee benefit program, use this:

if you acquired through an educational institution benefit, contact the institution.

If I cannot find product key, what else can I do. Can you assist me. Thanks
