;
; A few simple macros to handle installations on x64 machines.
;
; RunningX64 checks if the installer is running on a 64-bit OS.
; IsWow64 checks if the installer is a 32-bit application running on a 64-bit OS.
;
;   ${If} ${RunningX64}
;     MessageBox MB_OK "Running on 64-bit Windows"
;   ${EndIf}
;
; IsNative* checks the OS native CPU architecture.
;
;   ${If} ${IsNativeAMD64}
;     ; Install AMD64 64-bit driver/library
;   ${ElseIf} ${IsNativeARM64}
;     ; Install ARM64 64-bit driver/library
;   ${ElseIf} ${IsNativeIA32}
;     ; Install i386 32-bit driver/library
;   ${Else}
;     Abort "Unsupported CPU architecture!"

;       File "x86\myapp.exe"
;   ${Else}
;       Abort "Unsupported CPU architecture!"
;   ${EndIf}
;
; DisableX64FSRedirection disables file system redirection.
; EnableX64FSRedirection enables file system redirection.
