Why when I upgrade, I have to upgrade to 3 computers? I only want one and NOT willing to pay 36$ when I am only using 1 computer...

As far as I know you can purchase a subscription for any number of systems where the minimum subscription is the amount of systems that are currently registered on your account. On the purchase subscription wizard on the website you can move slider that controls the amount of systems you wish to buy back and forward.

I am only usng 1 computer but the minimum I can upgrade to is 3? Which is retared.. Cause I only want one..

From what i remember, the first three computers (not Server) are FREE.

 

If you have only 1 computer, why are you trying to upgrade to more than 1 computer?
