Windows 10: Unable to install .NET Framework 3.5

Hi, I have been having issues installing .NET Framework 3.5 on my PC, which I recently reinstalled Windows on to fix an issue with my original Windows install. Every time I attempt to install .NET 3.5 which I am using the administrator account for, I receive an "Access Denied" error.I tried the following remedies to no avail:1. Trying to enable .NET 3.5 from the Control Panel or installing it by opening an app that requires .NET 3.5 gave me error 0x80010108.2. Running the DISM /online /enable-feature /FeatureName:NetFx3 command in cmd gave me error 5. PowerShell also gave me an Access Denied

OK, the Windows 10 Feature installation method should have been straightforward, but since that errored out as well, something else seems to be going on with your Windows, so wait for somebody with more experience to suggest a way out.

In the mean time, if you haven't already, you could give muchomurka's suggestion a go as well with the elevated prompt and an install media to see if it works. The following link shows the detailed steps involved.

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.
