.Net 4.8 not getting installed in Windows 10

Question

Hi Team ,

In one of our customer machine we are not able to upgrade to .Net 4.8 from .Net 4.6.2

.Net 4.8 is not getting installed (we tried manually and through setup as well).

It shows the below error and also no windows updates pending in this machine .

Installation did not succeed with error

HRESULT 0x800f081e Error when installing .NET Framework 4.8.

As per the below link Windows 1607 Build 14393.2248 should support .Net 4.8

https://learn.microsoft.com/en-us/dotnet/framework/get-started/system-requirements

Could anyone please guide on this.

Thank You ,

Firstly did you confirm that NET 4.8 isn't already installed on the machine? It is possible an application already put it there.

Next, run the (NET Framework Repair Tool](https://learn.microsoft.com/en-us/dotnet/framework/install/repair).

After that collect the setup logs for the installer and look to see what is failing.

If nothing stands out, and you've done the standard stuff like disabling AV and rebooting and all that then consider installing an earlier version first (say 4.7.2) and see if that works. If it does then the installer may be corrupt so download it again and run it.
