How tell if the target is a 64-bit or not
Is there some way to create a script that tells whether the target computer is a 64-bit computer, and if it is, do some action that would not be done if it were a 32-bit machine?

Thanks in advance.

NSIS\Include\x64.nsh. Have you even *tried* searching? o_O

read help file chapter "4.2.3 Constants"


  ;Var BITVERSION

 ;Var ERROR

 ;32/64bit

 ;Call bitversion

 ;StrCmp $ERROR "1" jump_error

>Function bitversion

  GetVersion::WindowsPlatformArchitecture

  Pop $BITVERSION

  StrCmp $BITVERSION"64" bit64

  StrCmp $BITVERSION"32" 0 error

 ;bit32:

    SetRegView 32

    Sleep 500

    Goto done

  bit64:

    ;disable registry redirection (enable access to 64-bit portion of registry)

    SetRegView 64

    Sleep 500

    Goto done

  error:

   StrCpy $ERROR "1"

 done:

  ;messagebox mb_ok "'$BITVERSION'"

>FunctionEnd

You don't need to use GetVersion for this, just use x64.nsh as MSG pointed out.

${If} ${RunningX64}
  ...
${Else}
  ...
