How to make Innosetup uninstaller not run if installer is on?

Question

如果安装程序是通过Innosetup构建的，并且当前正在安装（安装程序和卸载程序是从同一源文件生成的），如何使通过Innosetup卸载程序创建的程序无法运行？

Answer 1

If AppMutex doesn't protect against this already, you can add code to both the install and uninstall to use CheckForMutexes() and CreateMutex() . If CheckForMutexes() returns true, you can then exit. this will essentially replace the AppMutex support and can check for your application too.
