存在一个与安全相关的问题，因此您需要编写自己的安全程序，该程序将随该exe一起附加.第一次运行时，它将在该exe中进行更改，因此它将不会在任何系统上再次运行.
并且还需要根据实现的安全性来修改设置/部署项目逻辑.

its an security related issue, so you need to write your own security program that will attached with that exe and when it will run first time it will make changes in that exe so it will not run again on any of the system.
and also you need to modified your setup/deployment project logic as per that security you implement.

您的PC是否允许您多次安装同一软件副本?我认为Windows不会允许它，除非您设置"removepreviousversion = true".

然后，如果要手动检查应用程序的存在，请考虑
关于在安装过程中在注册表中写入条目，并在尝试再次安装时阅读它...

Will your PC allow you to install same copy of software more than once? I don''t think windows will allow it unless you set "removepreviousversion = true".

Then, If you want to check the presence of your application manually, think
about writing an entry in registry while your installation and read it when you try to install it again...
