I thought I would also add that I just logged into my "Intuit" account which as a Quickbooks user, there is a good chance you have one. If you can find the username and password for your Intuit account then you can likely log in and find your 2011 Quickbooks. I used Quickbooks 2011 at one time and when I logged in not only did they have a record of my ownership of Quickbooks 2011 but they also had a download link for Quickbooks 2011 and they had my access key stored in my Intuit account. So you really should be able to get some of the hardest to obtain software and information pretty easily if you have an Intuit or Quickbooks username and password that works on the Intuit/Quickbooks website.
