How can I reverse a Windows Live Mail 2012 update?

I updated Windows Live Mail 2012 as recommended by Microsoft, as in an email it told me I must do this in order to continue sending and receiving email using Live Mail 2012. I am running Windows 7 and am NOT ready to upgrade to Windows 10. Live Mail was working fine until I downloaded the update and told it to "repair" the application :( How can I reverse this? I feel like Microsoft is intentionally making things worse for those of us that need and are still running older applications. Promoting a new product is one thing, sabotaging a perfectly functional older product is another thing all together. Any help I can get is appreciated.
