Question

所以我用以下命令运行我的安装程序：

C:\Program Files (x86)\Example\ExampleSetup.exe /VERYSILENT /SUPPRESSMSGBOXES /NORESTART

但是由于一些奇怪的原因，安装程序有50％的失败几率，当它失败时会返回0-3的随机退出代码。
我认为这可能是因为/VERYSILENT因为我在非静默运行时从未目睹过这种行为。
我也在SetupMutex部分中使用了[Setup]，那么它的崩溃时间是一半吗？
如果进程崩溃，我也想获得有意义的退出代码，以便我可以调试问题 这是日志输出：

所以我的具体问题是：为什么我的安装程序经常崩溃，我该怎么做才能解决这个问题？

Answer 1

我首先暂时删除“计时器”的东西。

计时器很快就会在快速静默安装完成时到期，因此mytimerproc正在尝试访问不再存在的窗口或者pascal脚本是引擎被破坏。

如果证明是这种情况（实际上即使没有），你应该解决这些问题：

您需要在安装程序关闭时销毁计时器（可能来自CurStepChanged(ssDone)）
您可能甚至不想在非常安静的安装中安排计时器，因为没有形式可以透明。
您应该在InitializeWizard中安排计时器，而不是在InitializeSetup，因为如果安装程序启动缓慢，当计时器到期时，窗口甚至不存在，否则会存在风险。

在无声模式下运行时，Inno Setup会频繁崩溃
