It seems as though I have successfully upgraded from 32 bit XP to 64 bit Windows 7, but I have a question. There are two "Program Files" folders, with one of them also reading "(x86)". After a bit of searching, I see that the x86 folder is for 32 bit programs (or something?). If I want a program to run in 64bit, do I have to specify which folder to install it in or will Windows pick the correct directory?
