Error 1603

I am having extreme trouble installing UE
Despite uninstalling MS C++ 2015 Redistributables I cannot successfully install.
I have clean installed Epic Installer and fresh copies of Both UE 4.11.1 and 4.10.4.

Help please!

Oh, I failed to add, that I am installing as admin, windows update is on and that windows 10 is up to date

Thanks again

So whats exacly happening?

Hi Shadow, thanks for replying
essentially every time I try to install UE the installation gets to the verification point, verifies then gets to prerequisites point and then hangs with the error 1603.
I did get error R5 yesterday (which is new) but still associated with the 1603 error.
