Windows 10: .NET FRAMEWORK 3.5 needed for an app.

hi. Please help.


I cannot use the Phillips plugin app which is needed for a Dialux software. It requires .NET FRAMEWORK VERSION 3.5 but I have version 4.5 and higher. I cannot Uninstall the new version of .NET FRAMEWORK 4.5 as it does not appear on the control panel. When I do run the older installation that appears it does not install the .NET FRAMEWORK version 3.5 and error 0x800F081F appears.

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,
