unreal engine -waitmutes-2015 exited with code 255
<p>when i make a new c++ project in ue4(doesnt matter version because same problem with most 4.8-4.11)it gives me:</p>

<p><em>The following modules are missing or build with a different engine version:UE4Editor-test.dll
Would you like to rebuild them now?</em></p>

<p>i press yes and it gives me:
<em>test could not be compiled.try rebuilding from source manually.</em></p>

<p>when i build the "source" in VS2015 , i get
<em>:MSB3073 The command ""C/:Program Files (x86)\Epic Games\4.11\Engine\Build\BatchFiles\Rebuild.bat" testEditor Win64 Development "C:\Users\usr\Documents\Unreal Projects\test\test.uproject" -waitmutex -2015" exited with code 255.</em></p>

<p>so i cant open the project made for C++ (no for blueprints) in the editor.</p>

<p>Any help appreciated!!</p>
