I have two development machines, XP Pro 32 bit, and Vista Ultimate 64. Real ice works fine on both. So, to answer your question, technically no - I don't *need* to use it on 64 bit windows, but as I'm migrating to that platform (and then on to windows 7, I suppose) it's very, very nice that it does work. Mainly due to the increased memory limit (like most here, I run many applications simultaneously while developing, and 8GB of RAM provides a noticable speed increase when switching from app to app). -Adam On Mon, Sep 7, 2009 at 9:26 PM, wrote: > Anybody need to use the microchip realice on 64 bit windows? > > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
