Tried .NET installation repair tool kit, and tried installation of .NET framework. Still didn't worked.

Tried the answer of How to reinstall .NET Framework 4/4.6 on Windows 10?

Still looking for new steps or a new repair tool from Microsoft to fix installation of .NET v4x in windows 10 18363.

  • I suggest doing Repair Install of Windows 10 with an In-place Upgrade.

  • .NET Framework 4.8 is already installed on the current version of Windows 10, which means .NET Framework 4.0 cannot be installed, since 4.8 is an in-place upgrade to 4.0. Your Windows installation is corrupt and you should do an in-place repair installation.

  • “Still looking for new steps or a new repair tool from Microsoft to fix installation of .NET v4x” - It is impossible to install or repair the .NET Framework 4.8 installation. Your only solution is to do a repair installation of Windows

Thanks to @Ramhound for 2nd link

Requested system administrator to allow windows update for the PC and new feature update through complete windows update enabled the .Net framework v4.8 in Window 10 Build18363 . Now All the applications that were throwing error is working now.

Also observed in the 'Turn Windows Features on or off' window. Its named as '.NET Framework 4.8 Advanced Services'.

This was '.Net Extensibility 4.8' before latest windows update.
