Unreal engine 4 doesn't launch

Hello
I’ve been using unreal engine 4 for a while but I had to change my hard disk and to download everything from the start.
But after finishing the download and trying to launching the engine it simply doesn’t start. I tried to open it using
UE4editor.exe but I have an error message Telling me api-ms-win-crt-runtime-l1-1-0.dll has not been found.
I looked up online and apparently I need to download the visual c++ redistruables and I already did install the redistruables of 2010,2013 ( in (x86) and (x64)) and the Unreal engine 4 downloader took care of installing the 2015 Redistruables and it still doesn’t work. I tried installing the 2015 from microsoft’s page but still the .Dll can not be found.
Thank you for help :slight_smile: i’m sorry my english is not the best

Hello Gafour,

This is still likely due to something related to your C++ 2015 Redistributables. You can usually fix this by downloading the Redists from Microsoft’s website, running the .exe, and using that to uninstall them. As soon as it finishes, just run the same .exe again and install them again. This should fix the issue for you.
