I recently set up a new copy of Windows 10 but I never bothered to install .NET Framework 3.5 because I thought I didn't need it. Then more recently, I tried to start up a favourite game of mine which turns out to require .NET Framework 3.5. I tried downloading it but I configured my OS, post-installation, in a way that blocks that from happening. There must be a way I can download files to install that program manually (and safely), right? Thanks.
