I bought the standard License roughly a year ago because i only had 1 computer(my Home computer) and it suited me perfectly.
I would now like to have one for my work computer as well. The Personal Home License seems to support what i would like. I'm wondering if i'm able to just upgrade my current standard License to the Personal Home License,(an additonal 10$) and if so how can i do that? Or can i not do that.

Thanks.
