mission impossible?

Was trying to install Engine 4.12.0 from past few days. but there are really a lot (A LOT) of errors to make it run.

-> Unable to Resume download. Code 0
-> Error Installing Prerequisites
-> MVSCP100.dll is missing (C++ 2010, 2011, 2013, 2015 were already installed on my PC)
-> MVSCP120.dll is missing
-> MVSCP160.dll is missing
-> and now finally …
-> 0xc000007 error

Is there any marathon of errors here? are any left after solving this. appreciate help for solving this 0xc000007 error.

Did you install the x64 C++ runtimes ?

It looks like the prerequisites installer failed.
Did you tell UAC to allow the prerequisites to run?
