[英]NSIS Installer with .NET 4.5
I'm after some code snippets for NSIS to detect and conditionally run the .NET 4.5 installer 我正在为NSIS提供一些代码片段,以检测并有条件地运行.NET 4.5安装程序
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 这个答案 - 带有.NET 4.0的NSIS安装程序 - 太天真了,因为只检查注册表项(而不是值)的存在不会区分4.0和4.5
You shouldn't check for an exact version number. 您不应该检查确切的版本号。 This will change in the future (as was the case for 4.0 > 4.5).
这将在未来发生变化(如4.0> 4.5的情况)。 Instead use the codes from the deployment guide .
而是使用部署指南中的代码。
In addition to that you should try to handle the reboot from .Net 4.5. 除此之外,您应该尝试从.Net 4.5处理重启。
