I had to uninstall MikTex, because it stopped working properly. Then I failed to install MikTex 2.9 on Windows 10 Pro N (64 bit). The message was: This app can't run on your PC. To find a version for your PC, check with the software publisher.
Even if hardware can run 64 bits a message such as "This app can't run on your PC" when combined with a secondary message about version such as usually indicates trying to load a 64bit app whilst the OS is 32bit. IF the Operating system is 32 bit you need to download MiKTeX from https://ctan.org/tex-archive/systems/win32/miktex/setup/windows-x86
(Personally I prefer the portable version)
