Hello Furney,
Thank you for visiting the Office Genuine Advantage forum today :-). Curious you mentioned buying Office online but you didn't receive any software whatsoever? Please let us know where you purchased the software from. Also before you install Office on more than one system you may want to read the End User Licensing Agreement "EULA" because you may not be able to install on more than one computer. Also have you tried to contact the company where you made the purchase and ask them to send you the product key?
There is not an avenue to see or get your Product Key from a computer. There are 3rd party applications available that would allow an end user to do this. We are unable to recommend any of them since it would be against our policy. A well phrased search in your favorite search engine should provide you the appropriate means.
Hope this helps you out.
Thank you,
Stephen
