Windows 10: Unable to enable .NET Framework

I need to use NetFramework 4.0 for a program ScanSpeeder. I have tried selecting it in Windows Features, but everytime it becomes unchecked. If I try to install a fresh download of NetFramework, I get an error message saying it is already installed and I need to turn it on in Windows Features.

Microsoft .NET Framework, Unhandled exception

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.

Regards,

Hi Larry,

The .NET Framework 3.5 is not automatically installed with Windows 10, and must be separately enabled to run applications that depend on it. To enable .NET Framework 3.5 and to know more about it, kindly access this

article. The article contains different steps you need to do to enable the .NET Framework 3.5. We suggest you do the
Install the .NET Framework 3.5 on Demand and the Enable the .NET Framework 3.5 in Control Panel
steps first.

Kindly share with us the result after you performed the steps found on the article we provided.
