How to manually install required Windows features when installation fails

Issue

During an Senstar Symphony installation, one or more required Microsoft® Windows® components fails and the following error may appear: “The installation of Additional Required Windows Features has failed. Setup will not exit”.

On newer Windows Operating Systems, including Microsoft Windows 8/8.1 or Windows Server® 2012, required components, such as .NET Framework 3.5 pre-requisites, may fail during installation.

Solution

Install required components manually via Windows.

Windows 2012 Server

2. When the Add Roles and Features Wizard opens, click Next.
   
   
3. On Installation Type, select the Role-based or feature-based installation option. Click Next.
   
   
4. On Server Selection, select the server where you want to install the missing Windows components (such as the local server). Click Next.
   
   
5. On Server Roles, click Next.
6. On Features, expand and select all of the .NET Framework 3.5 Features.

Troubleshooting Microsoft Windows

If you are unable to install required components manually, then a Windows-specific issue may need to be addressed before you can successfully install Senstar Symphony on the system. Such troubleshooting may require a system administrator.

For example, an issue with Windows Services or Windows Update may prevent you from installing required components.  Senstar creates a log file stored in the %TEMP% folder called EnableWinComponents.log that contains the output of the servicing tools during the Symphony installation. This log file may provide direction on how to troubleshoot Windows issues further.
