Environment
NetIQ Secure Configuration Manager 6.x
NetIQ Secure Configuration Manager 7.0
Situation
The SCM installer gives an error when you
have .NET 4.5 installed.
.NET 4.5 was installed on the core services
machine. The installer was launched. The prerequisite checker said
that .NET 3.5 was missing. The installer would not proceed.
Resolution
Please follow these steps to enable .Net framework 3.5 in Windows Server 2012, Windows Server 2012 R2, and Windows 2016.

• In Server Manager, click Manage and then select Add Roles and Features to start the Add Roles and Features Wizard.
• On the Select installation type screen, select Role-based or feature-based installation.
• Select the target server.
• On the Select features screen, check the box next to .Net Framework 3.5 Features.
• On the Confirm installation selections screen, a warning will be displayed asking Do you need to specify an alternate source path?. If the target computer does not have access to Windows Update, click the Specify an alternate source path link to specify the path to the \sources\sxs folder on the installation media and then click OK. After you have specified the alternate source, or if the target computer has access to Windows Update, click the X next to the warning, and then click Install.
If you are using Server Manager in Windows Server 2012 to add a role or feature to a remote server, the remote server’s computer account (DOMAIN\ComputerName$) requires access to the alternate source file path because the deployment operation runs in the SYSTEM context on the target server.
Cause
The prerequisite checker thought that .NET 3.5 was missing. It could not be installed since it already existed. The installer would not proceed since it did not appear that all prerequisites were met.
