Net Framework 3.5 Wont Install Windows 10

  

Problem

Windows 10 prompts that the .NET Framework needs to be installed.

But when you attempt the install using the ‘Download and install this feature’ the install fails.

Windows 10 prompts that the.NET Framework needs to be installed. An app on your PC needs the following Windows feature.NET Framework 3.5 (includes.NET 2.0 and 3.0) But when you attempt the install using the ‘Download and install this feature’ the install fails. The system I am doing the install on is a new fresh install of Windows 10. I have installed this Sage software on a laptop that was purchased with Windows 10 already on it and the.NET framework installed just fine. Not sure what the difference would be with this install. .NET Framework 3.5 is included in Win 10, so you couldn't install it from outside, no matter web installer or standalone installer. So, you may first check if the.NET Framework 3.5 is available in the Control Panel on Windows 10 Technical Preview and if available, you may enable it from the Control Panel to install it on the computer. I downloaded the.net framework 3.5 from Microsoft and tried to install it but it won't install on Windows 10. My system doesn't have access to the Internet because the wireless adapter is not working, that's why I downloaded the framework and tried to install it manually.

Solution

To fix this problem you will need to install the .NET Framework offline, from your Windows 10 install media. Xcode 8.3.3 dmg.

To be able to do this you will first need a Windows 10 install USB. If you do not already have this see Windows 10 – How to create a install USB.
