无法安装.net framework 3.5。 [英] Failed to Install .net framework 3.5.

问题描述

我创建了一个2012 R2 Datacenter VM。我试图安装.net framework 3.5，但它说源文件丢失了。我开始进行故障排除，并发现安全更新阻止了它。我查看了我的控制面板，查看了已安装的
程序，安全更新或应该删除安全更新的更新都没有。另一个解决方案是使用\sources \sxs使用备用源路径，但这也不起作用。有一篇文章说"如果
您在Windows Server 2012中使用服务器管理器将角色或功能添加到远程服务器，则远程服务器的计算机帐户（DOMAIN \ComputerName $）需要访问备用服务器源文件路径，因为部署操作在目标服务器上的SYSTEM
上下文中运行"但我不知道该怎么做。我也注意到通常在我创建的每个VM的资源下，也会创建一个.iso文件，但由于某种原因，它不再起作用了。我尝试重新创建服务器，但
同样的问题出现了

I created a 2012 R2 Datacenter VM. I tried to install .net framework 3.5 but it says the source file was missing. I started troubleshooting and figured it was a security update was preventing it. I looked in my control panel and looked at the installed programs and neither the security update or the update that was supposed to delete the security update was there. The other solution was to use an alternate source path using \sources\sxs but that doesn't work either. There was an article that says "If you are using Server Manager in Windows Server 2012 to add a role or feature to a remote server, the remote server’s computer account (DOMAIN\ComputerName$) requires access to the alternate source file path because the deployment operation runs in the SYSTEM context on the target server" but I'm not sure how to do that. I also noticed typically under resources for each VM I create, there will also be a .iso file created but for some reason, it doesn't work anymore more. I tried recreating the server but the same issue arises
