If you are using a Windows Server 2008 R2 system, or an earlier OS, you might find that you need to upgrade .NET Framework to the latest version.
Fortunately, the process is simple. Follow this link from your Windows VPS / Windows server to download the .NET Framework 4.5 update package directly from Microsoft: http://www.microsoft.com/en-us/download/details.aspx?id=30653
The updater will install the .NET Framework update on your system, or warn you if there are any missing requirements.
If you are using Windows Server 2012 R2, the system should already have the latest .NET Framework installed.
This process applies to:
- Windows Server 2008 R2
- Windows Server 2012 R2
