Hi,

I have installed DNN8 and given the folder permissions are per installation steps. Also I converted the folder to application in IIS.
The installation wizard runs successfully, but when I click "view website" I get following error;

DNN 8 requires .Net 4.5.1 or later being installed.

Hi,

I checked. .net 4.5.1 is already installed on my machine. Do I need to set it somewhere ?
