Hi,
IIS 7.5 does not have .NET 4.5 support by default, you have to manually install this. Firstly, you need to download .NET 4.5 from the Microsoft URL,
http://www.microsoft.com/en-in/download/details.aspx?id=30653Now, open Windows PowerShell and run this command to install this.
===================>>>
PS C:\Users\VPS1146858Admin\Downloads> Start-Process -FilePath "C:\Users\VPS1146858Admin\Downloads\dotNetFx45_Full_setup.exe" -ArgumentList "/q /norestart" -Wait
===================>>>
Now, you have successfully installed .NET 4.5 in your server.
Thank you,
