Configuration Error 
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. 

Parser Error Message: The 'targetFramework' attribute in the <compilation> element of the Web.config file is used only to target version 4.0 and later of the .NET Framework (for example, '<compilation targetFramework="4.0">'). The 'targetFramework' attribute currently references a version that is later than the installed version of the .NET Framework. Specify a valid target version of the .NET Framework, or install the required version of the .NET Framework.

Answer 1

Change this tag to 4.0:

<compilation targetFramework="4.0" />

and remove this tag:

<httpRuntime targetFramework="4.5" />

Answer 2

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.
