I purchased an Inspiron laptop from you in April 2013.  Recently, I was experiencing some challenges, and had a colleague who "knows computers" look at it (the laptop would not turn on at all).  This colleague erased all of the programs that I had on the machine, and reinstalled what he could.  

I currently have an icon for MS Office 2010, however after looking into what I had purchased (not the invoice, which would be helpful...), I noted that I am supposed to have 2013 version.  Unfortunately, I cannot find the activation key for the product that was installed on my laptop prior to purchase.  

 Is there any way I can reactivate MS Office on my laptop without having to jump through too many hoops?
