Merge 32bit and 64bit installer into one installer using NSIS

I have created a simple installer using NSIS. I want that the installer should detect the OS that a client is using.If a client is using a 32-bit OS then all the files should be copied to Program Files(32 bit) folder or else if he/she is using a 64-bit OS, all the files should be copied to 64-bit.Can anyone help me how to figure this out..

Thanks

Solution

  • Same as above (don't forget to include LogicLib.nsh and x64.nsh)

    Function .onInit

    ${If} ${RunningX64}
        StrCpy $INSTDIR "$PROGRAMFILES64\myProduct"
    ${Else}
        StrCpy $INSTDIR "$PROGRAMFILES\myProduct" ; $PROGRAMFILES32 also works
    ${EndIf}

FunctionEnd

    Optionally, you can also set the registry view (see SetRegView)
