If your version of Windows is 64-bit, you’re able to install both 32-bit and 64-bit software programs, so there are two different “Program Files” folders on your computer. However, 32-bit versions of Windows have just one folder, since they can only install 32-bit programs. Here’s an easy way to comprehend this… Two program folders exist on a 64-bit version of Windows:

32-bit location: C:\Program Files (x86)\64-bit location: C:\Program Files\

32-bit versions of Windows have just one folder:

32-bit location: C:\Program Files\

Therefore, if you find only one folder when checking this location, you’re using a 32-bit version of Windows. If there are two “Program Files” folder, you’re for sure using a 64-bit version.
