Can't resume 4.12.3 installation

So the launcher downloaded and verified 4.12.3 but it failed to complete installation. The “some prerequisites are missing” message popped up (it’s a new windows install and most of the C++ redistributables were missing( which is odd, since the launcher install is supposed to install them?)), so i went and installed everything manually and go back to the launcher to find the resume button, i click it several times but nothing happens. is there a way to make it work without redownloading the engine?
