Hello and Welcome!
"can i get the license of fmrte 17 with a pre paid visa or master card?"
Yes
"Also how does the activation process works?"
We have two activation processes available one online and one offline the online is as simple as going to the settings menu in FMRTE click on the "Activate" button copy and past your license from your Client Area , Next, Next and you are ready to use FMRTE.
For the offline option just follow the instructions on the following link: http://www.fmrte.com/offlineactivation there is also a video showing a step by step on how to do it.
"also if fmrte update do we need to activate it again?"
In some updates yes but this activation wont consume any activation from your license, and since we are on the activation subject please also note that each license comes with 3 activation just so we can be used on 3 different machines.
In case you have any more doubts let us know we will gladly help you out
