Hi,
Can I know from which portal you downloaded the trial version of Office? If you downloaded it from TechNet Evaluation Center, you should register with your Microsoft Account to continue, before downloading the product, you would be prompted with the product key, see the image below:
If you didn't keep the product key, visit the page http://www.microsoft.com/en-us/evalcenter/ again and register to continue, you will get the product key to activate your trial version. If you can't go on with your previous Microsoft Account, consider to use another to register.

Hi Melon,
I did download it through Technet. Your assistance was wonderful and everything is ready to go on my trial. Thank you so much!
