No. You could only do that when it was the current version (i.e. until CS6 was released).

Creative Suite is no longer sold (beware of swindlers!)

Today's solution is Creative Cloud, subscription only.

As said by @Test Screen Name, this is no more possible since a long, long time. There is no legal way to do that now. Anyone offering you support in this probably does offer a highly illegal solution.
