I just want to install the Mathcad Prime 2.0 received this week! There are two CD-ROMs, one for 64-bit Windows, another one for 32-bit, and I don't know which one to use? This PC is a Dell Vostro 420 and has got Windows XP, and Windows Vista (not activated).
Please, do answer me as soon as possible!
Thanks!
