NSIS安装程序使用.NET 4.5 [英] NSIS Installer with .NET 4.5

问题描述

我有些code片段后，我为NSIS检测并有条件地运行.NET 4.5的安装程序

I'm after some code snippets for NSIS to detect and conditionally run the .NET 4.5 installer

这答案 - NSIS安装程序与.NET 4.0 - 太幼稚如检查注册表项（不是值）只有presense 4.0和4.5之间不会歧视

This answer - NSIS Installer with .NET 4.0 - is too naive as checking only the presense of the registry key (not the value) will not discriminate between 4.0 and 4.5

推荐答案

您不应该检查一个确切的版本号。这将在未来的变化（如对于4.0> 4.5的情况下）。相反，使用C $ CS中的$从部署指南。

You shouldn't check for an exact version number. This will change in the future (as was the case for 4.0 > 4.5). Instead use the codes from the deployment guide.

另外，你应该尝试从.net 4.5处理重新启动。

In addition to that you should try to handle the reboot from .Net 4.5.
