.Net Framework Installation Error on EA 3.6.3/CA 2.1 and Windows Server 2016

Problem:

When installing Enterprise Analyzer 3.6.3 or COBOL Analyzer 2.1 on Windows 8, Windows 10, or Windows Server 2012 or 2016, you might receive an error that says the .NET Framework 3.5 could not be installed.

Resolution:

In this case, you must enable the .NET Framework 3.5 on the operating system.

1. Ensure that you have the installation media for your operating system accessible on the machine or on a mounted ISO.
2. Start a command prompt as an administrator by locating it on the Start menu, right-clicking, and selecting Run as Administrator.
3. For Windows 8, 10, or Server 2012, enter the following command:

Dism.exe /online /enable-feature /featurename:NetFX3 /source:F:\\sources\\sxs /LimitAccess

where F: is your installation media drive.

4. For Windows Server 2016, enter the following command:

Dism /online /enable-feature /featurename:NetFX3 /featurename:NetFx3ServerFeatures /Source:F:\\sources\\sxs /LimitAccess

where F: is your installation media drive.

On Windows Server 2016, you may need to restart the machine after these steps before running the installer due to the installation of MS SQL Server Express potentially requiring a restart.
