How do I Export my project properly?

Hi all guys. When i try to export my project and i check the minyfing script box, altought i have java 8 update 25 (64 bit) installed, construct 2 warn me that the minyfing script can't be done because i have the 32 bit java or because i don't have it at all, but i have it installed. So what am i supposed to do to export the project with the minyfing script?

Thanks and i apologize whether i made some mistakes, im Italian

Try reinstalling java and if construct 2 was open while you have installed java you need to restart construct 2 or you will get the same message every time
