Get your taxes done using TurboTax

This question / problem is obviously frustrating many TurboTax users.  And, unfortunately, Intuit / TurboTax support personnel just don't understand.  Really?   It's simple...  I purchased the TurboTax Desktop software which includes a License Code.  But, the purchased software is not compatible with my desktop computer hardware/software.  So, I cannot load and run the Desktop software!  Given, I already purchased a license, I want to use that license to access the TurboTax OnLine system.  But, NO can do!  I must now buy the OnLine version.  Intuit - That is ridiculous and insane.  HELP!
