MultiArch on Windows


Under Windows 64-bit (Vista-64, Win7-64, Win8-64 and Win10-64),






The WOW64 interface needs to ensure that files and registry settings for 32-bit applications are kept apart from those for 64-bit applications. To achieve this two mechanisms are used, File and Registry Redirection and Key Reflection. Redirection maintains logical views of the data as if it were in 32-bit Windows and maps it to the correct physical location. Reflection ensures that 32-bit and 64-bit settings will be consistent where that is required.

File redirection ensures that there are separate folders for program and operating system files for 32- and 64-bit applications.

32-bit applications files are installed into

C:\Program Files(x86)

32-bit system files are installed into


For 64-bit applications, files are installed to:

C:\Program Files
