Sysnative “folder” on Windows

“SysNative” isn’t a real directory. It gets redirected to the real “System32” directory by the WOW64 emulation system. Only 32-bit applications running on 64-bit Windows via WOW64 can use this virtual directory. A 32-bit application running on 32-bit Windows cannot use “SysNative”, so “System32” has to be tried even in a 32-bit app.
