Hello,
I'm wondering if I can get the most recent update of Mathematica 10.4. I cannot find it within Wolfram User Portal.
Kind Regards, Mathias
According to Wolfram Support, the upgrade from 10.3 to 10.4 is a paid upgrade. From the Store page, by entering my activation key, I found out that the upgrade from 10.3 to 10.4 is 95 excluding VAT. Hope this helps other people too.
I would like to know this, too.
