The Windows 64-bit operating system and the 32-bit operating system are a little different on the registry

The Windows 64-bit operating system provides compatibility with 32-bit applications and retains many 32-bit tools in the "C:\Windows\SysWOW64" directory (for example, CMD.exe is 32-bit). When running 32-bit applications on a Windows 64-bit operating system, operating the registry, searching for a directory, Microsoft passes the Reflection (Reflector) and will "\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\ Uninstall "replaced by" \\SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall ", That is, the Wow6432node is appended to the software. So if it is a 64-bit script, on a 64-bit operating system, through the registry operation of 32-bit applications, you have to manually fill in the code "Wow6432node", otherwise it will not be found.

1. The Wow6432 registry entry indicates that you ' re running a 64-bit version of Windows. The OS uses this key to present a separate view of HKEY_LOCAL_MACHINE\Software for 32-bit applications so run on a 64-bi T version of Windows. When a 32-bit application queries a value under the Hkey_local_machine\software\<company>\<product> subkey, T He application reads from the Hkey_local_machine\software\wow6432node\<company>\ <product> subkey.
