Hi Mutual - Documentos OneDrive,  

Thank you for reaching out to Microsoft Q & A forum. 

The error "HRESULT 0x800f081e" when installing .NET Framework 4.8 on Windows Server 2016 usually means the feature is already installed, disabled, or blocked by system policies. Try these steps to resolve it: 

1.Check if .NET Framework 4.8 is already installed: 

Run the following in PowerShell (Admin): 

Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" | Select Release

If the release number is 528040 or higher, .NET 4.8 is already installed, and no further action is needed. Otherwise, proceed with the next steps.

2.Enable .NET Framework 4.8 manually: 

Open PowerShell as Administrator and run 

DISM /Online /Enable-Feature /FeatureName:NetFx4

3.Ensure Windows Server is fully updated: 

Go to Settings → Update & Security → Windows Update and install all pending updates,

4.Try the offline installer: 

Download the .NET Framework 4.8 installer from the Microsoft .NET Download Page. 

5.Repair system files if needed: 

Run these commands in Command Prompt (Admin): 

sfc /scannow  
DISM /Online /Cleanup-Image /RestoreHealth
