I am updating .net on 5 servers with .net 4.8. 4 of them installed with no problems, I have one that keeps giving me: .net framework 4.8 has not been installed because:
HRESULT 0x800f081e I have checked and windows updates are up to date, the dism health check says no compoonene store corruption detected.

Why won't it run on this one server? What do I need to check/fix?

    Have you checked what is said in CBS.log and DSIM.log?

    @Rex Winkler , with checking Windows Updates and DISM Health Checks, I wonder if it's already installed and pending a reboot. It's a fairly generic error and you've already looked down the right path. Were the five servers identical? Also, were you installing from offline media and this server had Internet access issues?

    Hi @Rex Winkler ,

    The .NET Framework 4.8 can be installed on your Windows Server 2016. After ensuring you have completed all pending Windows Updates, please try to use the .NET Framework Repair Tool to repair your .NET Framework. Then, please refer to: How to determine which .NET Framework versions are installed to verify which versions of .NET Framework is already installed on your computer.

    If it persists, could you share us more log files in order for us to investigate it further? You could download and run this collect.exe tool, go to %temp% folder and find the vslogs.zip file, upload it to https://onedrive.live.com/ and share the link here.

    Sincerely,
    Anna
