Windows Server 2012 is natively supported through the installation process starting with version 7.5.15. When installing previous versions on Windows Server 2012, however, you must manually configure the Application Pool in IIS to use the .NET v2.0 Framework Version. If this manual configuration is not performed, an error will be received when attempting to launch the application.
After installation, to configure IIS to use the v2.0 Framework Version, perform the following:
1.Launch the Internet Information Services (IIS) Manager.
2.Expand the applicable server in the left panel.
3.Select Application Pools.
4.Right-click the application pool you wish to edit, and choose Advanced Settings.
5.Click to edit the .NET Framework Version and change the value from v4.0 to v2.0.
