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?
I have windows 7, 64b and i don´t update it.
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 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
