1st: jv16 X work fine in win 8.1 64 bit.
2nd: in win 7 32 bit stuck in About Windows and I have to close with Ctrl+Alt+Del.
3rd: in win 7 the best realease is again 2011.
4th: I've a an old VIP key for life, but don't works with X, so I had to buy another license.
So, in win 7 I'm running an very old version, and in win 8 the new one.
Just for fun, the best jv16 was free some year ago . ;-)
Good luck from Venice Italy.
