crash - Inno Setup 在静默模式下运行时频繁崩溃

Question

所以我使用以下命令运行安装程序:

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

但由于某些奇怪的原因，安装程序有 50% 的几率失败，当失败时，它会返回 0-3 之间的随机退出代码。
我认为这可能是因为 /VERYSILENT 因为我在非静默运行时从未见过这种行为。
我还在[Setup]部分中使用了SetupMutex，那么是否会出现一半时间崩溃的情况？
如果进程确实崩溃，我还希望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，我能做些什么来解决这个问题？

Answer 1

我首先会暂时删除“计时器”内容。

计时器可能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 脚本引擎正在被破坏。

如果事实证明是这样(实际上即使不是)，您应该解决这些问题:

• 您需要在安装程序关闭时销毁计时器(可能来自 CurStepChanged(ssDone))
• 您甚至可能不想在非常安静的安装中安排计时器，因为没有任何形式可以使其透明。
• 您应该在 InitializeWizard 中安排计时器，而不是在 InitializeSetup 中，因为您可能面临窗口甚至不存在的风险，否则，当计时器到期时，如果安装程序正在启动慢慢来。
