Not sure whether this is an issue with win 10, or whether the computer you're working on has a high dpi screen.  I've had trouble with the high dpi screens, and have found I had to put the screen in a more normal resolution temporarily to install and register spss. Once installed it seems on at higher resolution. (I've run into this issue on win 8 machines before).

  When I get to authorizing SPSS on win10, the dialog boxes are
far too small to be useful.  In particular, the input box for the
auth code itself is invisible.  If I click around the area where I know
it should be it sort of appears, but so far I haven't been able
actually enter text.

SPSS itself is OK screen wise but barfs at the lack of a license or
30 day trial.

Since SPSS uses Java I start to wonder if that is where the problem
lies?

Thanks for any ideas...
