Hi, This is Ramesh.
The error code 0x80070490 can usually be resolved by removing .NET Framework 3.5 and reinstalling it.
From the admin Command Prompt, run:
dism /online /disable-feature /featurename:NetFX3
Restart Windows.
Then run the following command to reinstall it:
dism /online /enable-feature /featurename:NetFX3 /All
Note:
If that doesn't help, we must use the DISM /Add-Package method to install it. See the accepted solution in this link:
