You have  64-bit Windows, meaning you can run either 64-bit programs (Program Files), or 32-bit programs (Program Files x86).      More here: [URL] The "x86" started with Intel processors (8086, 80386, etc.), and x86 stuck as a name for anything compatible with that standard.    If MS had called the folders "x64" and  "x32" instead, it would've been easier, but so it goes.
When I open the C drive it has two folders: Program Files, and Program Files (x86).  Whats the x86 about.  I don't remember making it.  Thanks anyone.
