How tell if the target is a 64-bit or not

sethradio · 2nd February 2012, 04:39

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"

PHP Code:


			
  ;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.

code:
${If} ${RunningX64}

  ...

${Else}

  ...

Can't believe I completely forgot about x64.nsh.
