It is not easy to buy something from Microsoft, if you live in Serbia.
In my case it is a A+VCE program.
What you need :
* Microsoft account
* Valid payment method (PayPal, credit card for Internet payments…..) which you put under your MS account
* WIN 10 PC (software demand, and this is what I chose) or Android
* Valid license for WIN 10
* Configured WIN 10 :
Control Panel/ Regional and Language settings set your Time Zone and (a MUST) country (if you do not, it will always ask for a payment method, although you have entered a valid one).
And then you buy A+ VCE using the program itself, and use Serbian Microsoft Shop!
