Hi,

Welcome to Microsoft Community.

I suggest you to un-check and recheck .Net framework 3.5 and .Net framework 4.6 advance series from Windows features.

Try the following steps:

• Press Windows + R keys to open Run command.
• Type Appwiz.cpl and select "turn Windows feature on or off" from the left
• Uncheck .Net framework 3.5 and .Net framework 4.6 advance series.
• Restart the computer
• Repeat step 1 and 2 and check .Net framework 3.5 and .Net framework 4.6 advance series.
• Restart the computer.
