Hey. When I want to launch the program, it shows the error : The pplication was unable to start correctly (0xc000007b). What´s wrong with it ?? somebody can help me?
What is your OS? 32b or 64b?
My OS is 64b
What is your OS? If it’s Windows, did you update recently?
If you don’t update windows then you probably don’t have the C++ redistributes from Microsoft. I would check your control panel if you have them under uninstall programs option.
I have windows 7, 64b and i don´t update it.
I installed c++ redistributes but it didn´t do anythink
You definitely need SP1 and .NET Framework:

thank You. i will try it.
it doesn´t helped it still shows this error.
It seems to be a pretty common issue, potentially completely unrelated to UE4. Have a look at this, perhaps some of it will apply to your case:
If nothing else works, keep googling. A quick search gave me plenty of options with folks confirming that some worked for them.
I tried everything except for re-intalling program. i uninstaled it and now it is installing. I will see if it work. thanks. 
it didn´t worked 
Are you running an nVidia card by any chance. It might be something as strange as a corrupted driver. What is in your PC?
I don’t know what is in my computer. I’m not home today but I will be tomorrow. So i will check it
