Cannot install feature "Centralized SSL Certificate Support" on Windows Datacenter 2019

Question

My email server (SmarterMail) upgrade needs the Windows feature "Centralized SSL Certificate Support" in order for it to work. I am running on Windows Datacenter 2019. When I try to install the needed feature (through server manager Add Roles & Features, under the Security node) it fails with "The referenced assembly could not be found. Error: 0x80073701" So I have no email at this moment, except my Gmail backup email address.

I have run SFC and DISM with the parameters that Microsoft specifies, and have rebooted the server, but the same error keeps happening. I would try PowerShell with the "Install-WindowsFeature" command, but I am not sure how to refer to the needed feature, and I am not sure it will work anyway.

Is there any other secret to allowing this one little feature to get installed?

Hello

Error 0x80073701 usually indicates a missing system file. Here are a few additional steps you can try:

1.Specify Source Path:

When running the DISM tool, specify the source path to the installation media.

Open Command Prompt as Administrator and run:

DISM /Online /Cleanup-Image /RestoreHealth /Source:E:\sources\sxs

Replace E:\sources\sxs with the correct path to your installation media.

2.Repair Install:

Consider performing a repair install of Windows Server 2019. Run the setup.exe from the root of your installation media. This can help restore any missing files.

3.Windows Update Troubleshooter:

Use the built-in Windows Update Troubleshooter to identify and fix issues with Windows Update. Go to Settings > Update & Security > Troubleshoot > Windows Update.
