Unreal Engine Install Failed - necessary prerequisites have failed to install

I had some technical issues with Unreal Games Launcher so needed to uninstall everything including unreal engine etc. I removed all the registry files too. Once I reinstalled the launcher and finally got it logging in I moved on to loading unreal engine… and ran into more trouble.

I have gone through all the steps recommended in the help link and am still having no success in getting past this error message.

I am including both trouble shooting logs. Can anyone see from them what might be causing the problem? Thanks for reading!

Related to the above problem do I need to have visual 2013 express for windows 7 or will visual 2015 do the trick?


I’m sorry that you are having an issue with the Epic Games Launcher.

Thank you , I will email them my findings and questions. On the subject of VS 2015 I have already uninstalled and reinstalled c++ redistribution of 2015. That seemed to have fixed some small quarks in my dxdiag editor but not the missing prerequisites for unreal engine :(.

Thanks again. Any updates on what I eventually find out is the the problem I will add to this thread for anyone else that has the same issues.
