I\'m updating my operating system to Windows 7 x64, I only have experience with running 32-bit operating systems. Does anyone have any bad/good experiences with a 64 bit en
I wouldn't worry too much, if each program has an x64 download link, then use that. If not then your code will run through WOW64 emulation. And it will seem to you like it is running like normal.
Please see this related question I answered about 5 minutes ago.
WOW64 refers to windows32 on windows64 and it is a transparent emulation laywer that allows x86 programs to run on x64 operating systems. WOW64 will automatically be used if you run an x86 Windows program on an x64 Windows operating system.
