I have upgraded my current laptop that I use for programming with CCP to windows 8.1, but installed 32 bit version. Use 64 bit on my desktop where I do most of the programming, mostly use the laptop just for downloading to remotes on site. If I remember correctly using 64 bit will allow me to download to remotes, but not to MSC-400. Laptop now needs replacing, and the one that I am probably going to replace it with has 64 bit windows 8.1 on it. Does anyone know if the CCP program has now overcome the obstacle preventing it from working fully on a 64 bit version of windows, or do I need to find a way to get a 32 bit version of windows instead?
