How to detect if system is 32bit or 64bit
How to detect in NSIS in a simple way if system is 32bit or 64bit? Thanks for any hints.

Try searching next time...

!include x64.nsh

outfile test.exe

Section Test
        ${If} ${RunningX64}
                MessageBox MB_OK "running on x64"
        ${Else}
                MessageBox MB_OK "running on x86"
        ${EndIf}
SectionEnd

You can try this too:

GetVersion::WindowsPlatformArchitecture
Pop $R1

${If} $R1 == "32"
   MessageBox MB_OK "32 bits"
${ElseIf} $R1 == "64"
   MessageBox MB_OK "64 bits"
${Endif}

Keep in mind that GetVersion::WindowsPlatformArchitecture requires the GetVersion plugin, which doesn't ship with NSIS.
http://nsis.sourceforge.net/GetVersi...ows%29_plug-in

Overall I'd say use x64.nsh (and WinVer.nsh for other windows version bits checking) before poking at the plugin.
