如何在 NSIS 中获取 VC++ 2005 的正确返回值/状态

Question

我想用 NSIS 静默安装 Visual C++ Redistributable Packages for Visual Studio 2013。

但是，没有返回正确的退出代码。我测试了几种类型的变化。我想出的最好的是：

DetailPrint "Installing VC++ 2005"
    File "${STOCKINPUTFOLDER}\bin\Debug\vcredist_x86.EXE"
    ClearErrors
    ExecWait "$OUTDIR\vcredist_x86.EXE /q:a /c:$\"msiexec /i vcredist.msi /qb /norestart$\"" $0 ; also can use /qn 

    ;do not delete the file out-rightly so that evaluation of IfErrors below is clean           
    IfErrors execError noError

    execError:
        Goto ShortEndInstall

    ShortEndInstall:
        MessageBox MB_OK|MB_ICONEXCLAMATION "ShortEndInstall"
        Delete "$OUTDIR\vcredist_x86.EXE" ;we did not delete the file outrightly so that evaluation of IfErrors is clean
        Quit

    noError:
        ${If} $0 != 0
            MessageBox MB_OK|MB_ICONEXCLAMATION "You did not complete the installation of the VC++ 2005 re-distributable. Installation will now abort. Return code $0"
            Goto ShortEndInstall
        ${EndIf}

        MessageBox MB_OK|MB_ICONEXCLAMATION "No error"
        Delete "$OUTDIR\vcredist_x86.EXE" ;we did not delete the file outrightly so that evaluation of IfErrors is clean

但是当我故意点击VC++2005安装的“取消”按钮时，NSIS仍然认为安装成功（我在指令MessageBox MB_OK|MB_ICONEXCLAMATION "No error"得到对话框）

我怎样才能准确正确地获得返回的错误（例如，当我自己“取消”安装时）？

编辑：

在@Anders 的帮助下，我现在得到了以下内容，但仍然失败（即not installed，即使 VC++ 2005 安装已完成。我还尝试了不同的命令行选项来安装 VC++2005）

也许 vcredist_x86.exe 没有从 MsiExec 正确返回退出代码？

如果ExecWait 能够找到并启动进程（IfErrors 为“false”），则 NSIS 保证从子进程返回正确的退出代码。

$0 != 0 实际上是一个字符串比较，您应该使用$0 <> 0 比较 32 位数字，但在这种情况下不是问题。

!include LogicLib.nsh
Section

ExecWait '"cmd" /c exit 0' $0
${If} ${Errors}
${OrIf} $0 <> 0
    Abort "Error, child process exited with $0" # Will not abort here
${EndIf}

ExecWait '"cmd" /c exit 1234' $0
${If} ${Errors}
${OrIf} $0 <> 0
    Abort "Error, child process exited with $0" # Will abort here
${EndIf}
