  1. Open Server Manager.
  2. Click Manage > Add Roles and Features.
  3. On the "Features" tab, look for .NET Framework 4.6.2. (Note: If 4.8 is installed, it often supersedes the entry, or you can check via the Registry).

Post-install recommendations

  • Run Windows Update to pick up any .NET security or servicing fixes.
  • If you manage many servers, consider deploying the offline installer via Group Policy, Configuration Manager (SCCM), or a scripted tool (PowerShell + PSRemoting).
  • Test critical applications in a non-production environment after installing .NET 4.8.

Step 3: Troubleshooting Common Issues

While the installation usually proceeds smoothly on Windows Server 2016, you may encounter specific errors.

Method 2: Silent Installation (For mass deployment or scripting)

ndp48-x86-x64-allos-enu.exe /q /norestart
shutdown /r /t 30 /c "Rebooting to complete .NET Framework 4.8 installation"
