    How can I replace Net Framework 4.5 with 4.0 in Windows 8.1?

    So far I can disable and re-enable Net Framework 4.5 on "Turn Windows Features on or off", but I'm unable to manually install Net Framework 4.0 or Uninstall 4.5 beforehand since there is no option to remove it.

    Net framework Repair tool doesn't include an uninstall option and the methods listed here don't affect my Windows 8.1 installation.

    What I'm missing?
