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

[sethradio]

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

;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}
...Stu

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