The number at the back is belongs to the Operating System itself Not for word. If you purchase is bundled check with your reseller If its full version or trial. even if trial reseller should provide the Key. Also you can contact to Microsoft to verify.

Good Luck

Showing invalid certificate

I tried everything suggested above and on other sites, which included updating time and date, cleaning history, cleaning registry, re-installing Chrome, downloading new certificates from Microsoft. Nothing worked. I went to my Antivirus Program (Bit Defender). Under "Privacy" find the switch for "Scan SSL" Turn switch off. Now Chrome works great!

If you have entered the product key correctly as shown on the Certificate of Authenticity label, then perhaps the key has already been registered by someone else / used on a different computer.

If you are looking for an alternative Office Suite that can open and process Mircrosoft Office documents including the latest .DOCX formats, then why not try using the Kingsoft Office Suite 2012 Free which doesn't need a product key and works very well.
