Just a simple question - I'm running the x64 Build 25329 - I haven't had any *real bad* problems and my downloads are much improved over the 32-bit current release build. Now I have the 25570 build downloaded and just wondered if I should un-install the current build I have before installing the 25570 build? Or can I just install over top of the current one? Years of experience have taught me to *always* un-install first, but I just wanted to check before I possibly screw up. Thanks for any reply, and for the hard work that goes into the software. Thanks! NSK
