You have to update your application pool to .net 4.0 in IIS. It's probably set to 2.0 currently.
您必须在 IIS 中将应用程序池更新为 .net 4.0。它目前可能设置为 2.0。

Chances are IIS doesn't have 4 installed (or if it is the site isn't specified to use it). Assuming you're running IIS7 have a look at this post:
可能是 IIS 没有安装 4（或者如果没有指定站点使用它）。假设您正在运行 IIS7，请查看这篇文章：

I had similar issue installing nopCommerce 2.80 on server. I use IIS7 net. 4.0 integrated pool. And just installed .net 4.5 from WebMatrix Products->Frameworks section. Restart will be required. Then it started to work.
我在服务器上安装 nopCommerce 2.80 时遇到了类似的问题。我使用 IIS7 网络。4.0 集成池。刚刚从 WebMatrix Products->Frameworks 部分安装了 .net 4.5。将需要重新启动。然后它开始工作。

Change this tag to 4.0:
将此标签更改为 4.0：
<compilation targetFramework="4.0" />
and remove this tag:
并删除此标签：
<httpRuntime targetFramework="4.5" />

You just need to upgrade your .NET framework to ver 4.5 in your IIS 7.5 server you do that using the Microsoft web installerdo a search for .NET and then installed the .NET framework version 4.5 and the all the apps that target that version will work
您只需要在您的 IIS 7.5 服务器中将您的 .NET 框架升级到 4.5 版，您可以使用Microsoft Web 安装程序来搜索 .NET，然后安装 .NET 框架 4.5 版，并且所有针对该版本的应用程序都将工作

you have to install .net framework 4.5 then it will works fine. "targetframework" attribute is not recognized by .net framework 4.0. So run the following command on command prompt and check either .net version 4.5 in installed on hosting machine or not.if not then install .net framework 4.5.it will work fine. run this command on cmd as follows.
您必须安装 .net framework 4.5，然后才能正常工作。.net framework 4.0 无法识别“targetframework”属性。因此，在命令提示符下运行以下命令并检查主机上是否安装了 .net 版本 4.5。如果没有，则安装 .net framework 4.5。它会正常工作。在 cmd 上运行此命令，如下所示。
wmic /namespace:\root\cimv2 path win32_product where "name like '%%.NET%%'" get version
