Launcher fails to start UT4

I just installed the latest UT4 update and immediately prior to that the games launcher update. While this was happening I was in the marketplace getting the newly released maps.

Now, when I click on Launch for UT4 it goes through the usual stage where the button will gray out and show “Busy.” But then after some time without launching the game or giving any kind of error code or message the button will revert back to the original “Launch” prompt.

I’m not sure what is happening any help would be greatly appreciated. And, I will be happy to provide any extra information.

I’m sorry about that,but i can’t help it.
Ii got same error, and now it is impossible to run UT4.
I ré-installed the launcher and UT4, but since last launcher update, i can no more run UT4.

Thanks everyone. I was looking into the issue at the unreal tournament forums and it turns out they have already recognized the problem and have proposed a fix: install Visual Studio C++ Community Redistributable 2015.
