推荐答案

这必须是不可能的，因为用户可以随时进行运行它之前的安装包复制。一个包（类似* .msi文件）仅仅是一个字节序列，可复制...

This must be impossible as the user may always make a copy of the installation package before running it. A package (like an *.msi file) is just a sequence of bytes, that can be copied...

您可以将其限制在每台机器上安装2鉴于你留下的地方的一些信息（如注册表）。

You can limit it to 2 installations per machine given that you leave some information behind somewhere (like in the registry).

另一种方法是有一个授权密钥（或嵌入到安装包中的键）的，则使用使用因特网上的中央服务器来激活软件。这可能是你唯一的选择。

Another alternative is to have a license key (or a key embedded into the installation package) that then is used to activate the software using a central server on the Internet. That is probably you only option.
