Can anyone please explain to me how I can upgrade my platform to build 220 without losing all my templates and files?

I have vista and it never upgrades for me automatically. I'm not sure if I need to delete old version before upgrading manually. And I surely don't want to download all my indicators and templates all over again. I have my platform charts all layed out in a certain way and would take me forever to re-do everything.

Thanks much for any advice.
