Just wondering, is your computer actually still 32-bit or did you install a 32-bit operating system for some other reason? At least for desktops I think you'd need to have a Pentium 4 or earlier to still be limited to 32-bit. But I'm glad the Windows XP version helps you, just be aware that not everything works regarding the scripting support (I should probably add a warning about this to the manual).

The two Windows 10 computers I bought from HP just a couple of years ago came with a 32-bit OS. The Windows 7 install CD is 32-bit as well. Funny thing is, all the processors are 64-bit. Microsoft probably just should of made Windows 10 64-bit only if that's the move everyone wants to make. I personally don't see the benefit of 64-bit unless you really need a lot of memory. Gaming, 4K editing, 3D rendering, and so forth. Anyways, it looks like 32-bit will still be around for a while if Microsoft is going to sell/distribute a 32-bit OS.
