Windows 10: Installing Microsoft .NET Framework 3.5 on a Windows 10 computer

I tried to install an (old) software on my computer and got the message: "Microsoft .NET Framework 3.5 SP1 was not found on your system. It is required in order to complete the installation. You can download and install the required version of .NET by visiting
microsoft.com/downloads/details.aspx?FamilyId=AB99342F-5D1A-413D-8319-81DA479AB0D7displaylang=en"

I followed the link but got a 404 error. I found a download site at https://www.microsoft.com/en-us/down...ils.aspx?id=22. However I'm concerned as to whether the 3.5 version can coexist peacefully with the presumably later version I have on my Windows 10 v. 6.1 computer. Any advice? Thanks.

I suggest you to turn on .NET Framework feature and check if it helps.

• Press Windows + R keys from the keyboard.

• Click on Turn Windows features on or off from the left pane.
• Check if the .NET Framework 3.5 (includes .NET 2.0 and 3.0)
  option is available in it.
