When you create a project in C++ gives an error.

Hi all. When you create a project in C++ displays an error.

The project failed to compile with this version of the engine. Build output is as follows:

From all this I realized that the error is likely due to the lack of some library.

Do you have the Windows SDK installed? If you already have it, you may need to add it to your system paths.

3

Directx SDK?

4

I have this file for example here:

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include

edit: To answer your question, I guess it’s called Microsoft Windows SDK.

5

The SDK I installed. And the error remained.

6

Are you sure, that the path to your Windows.h is in your system variables?

You should have a system variable which is called “INCLUDE”, which should include “C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include” and more.

7

Where exactly is this way possible to register?

8

I’ll make a video as this error occurs.

9

Just search in windows for “Environment Variable”. But please be careful, do not delete any existing path. There you should find a variable called “Include”. The value of this variable should include the path to your SDK Include folder. Only if this path is set Visual Studio can find your Windows.h.

You incorrectly have understood my problem.
Here’s a look at this video: https://youtu.be/4tCIL-6bBBQ

12

in the error message you can clearly see that Unreal Build Tool (UBT) has problem with your user name, because it contains special characters (seems to be Russian), similarly to my user name (Iván)

  1. do not place you project under your user name, VS won’t compile too.
  2. you use an old version 4.7.2. I personally started a thread on Answerhub and took part in fixing this issue when 4.7 was the actual version, because it totally prevented Hot Reload to work, even if the project was e.g. at C:\UE\TestProject, because UBT during Hot Reload put some temporary stuff under user folders. Finally it was fixed around 4.7.5 or later, the last 4.7 edition or 4.8 are definitely good, you can search release notes or my thread on Anwerhub.

Good luck :slight_smile:

13

As I understand it the user name must be in English. In any which case, thanks, I will try to do something.

14

yes, if you want to place a project into the user folder or its subfolders.
and to get hot reload work, you need a newer engine version.

15

I am facing the similar problem too , Please let me know the method you followed to solve the problem

thank you.

16

Try to compile the project using Visual Studio Express 2013 or Visual Studio 2015 (depending on engine version). I just have the no versions of Visual Studio.

17

I am using the latest version

18

I got my problem solved
i changed my project file location and it worked
i have no clue how

19

I understand from all of this that you need to download a new version of the engine or to download Microsoft Visual Studio 2015. But downloading a new version of the engine got this error.
Error starting the application (0xc0000007b). To exit the application, click “OK”.

Installed Unreal Engine version 4.12.5. The previous error disappeared, but appeared new problem.

The project could not be compiled. Would you like to open it in Visual Studio?

First of all make sure you’re using Visual Studio 2015, the 2013 is not supported anymore in the new versions (4.10+ I think).
Second make sure at install it you enable the VC++ and if there are DirectX settings in the installer too.

Edit: If you create a clone of a project make sure you remove the folders Intermediate and Saved from the game project, remove it or move to a subfolder then close the VS and reopen and try to compile anothertime.

*The classes and other properties have changed since the version 4.7 to 4.12 you will have problems, make sure you try to use a new sample created in the 4.12 and no use other project name.
