Hello MBAZABAS,
From looking at your log file, this seems to be the main cause of your issues:
MainFrameActions: Cooking (Windows): WindowsPlatform.get_Compiler: WARNING: Visual C++ 2015 toolchain does not appear to be correctly installed. Please verify that “Common Tools for Visual C++ 2015” was selected when installing Visual Studio 2015.
This is appearing due to not having Visual Studio 2015 installed and/or not having all of the necessary components to use it with UE4. If you do not have it installed, please download the installer from Microsoft’s website here. There are a few choices, while only Express, Community, and Professional are supported for UE4. Community is the most generally used choice but be sure to review its terms of use before deciding on a version.
If Visual Studio 2015 is installed, please open your Control Panel > Programs and Features and select Microsoft Visual Studio 2015 and click “Change”. Once the setup opens, click “Modify” and you’ll see a list of components. Please check the box for “Common Tools for Visual C++ 2015” under the “Visual C++” tab. Please note that this is not the same as the option below called simply “Common Tools”.
Once these features have been installed, you should be good to go. If this is a blueprint project and you’re wondering why you need Visual Studio, this would be due to some of the plugins you are using requiring compiling when you attempt to package. One example is the Oculus plugin. You can find other examples of this in the log by searching for the words “Error” or “Warning”.
Hope this helps!
im having the sam e problem and i try this solution but nothing happnes 
Hello andresmedia,
Your issue doesn’t seem to be associated with the one that MBAZABAS was experiencing. The “Class None” error doesn’t really mean anything as far as I know and I’ve only seen it as a symptom of other problems rather than a cause.
The main error in your log seems to be:
UnrealBuildTool: c1xx: fatal error C1083: No se puede abrir el archivo intermedio para compilador: 'Z:\CREATIVE\DISE?‘OS\3D\UNREAL\VR\vr1\Intermediate\Build\Win64\vr1\Development\UELinkerFixups\UELinkerFixupsName.h.pch’: No such file or directory
which could be caused by the unrecognized symbol in your file path, in the folder name: DISE?'OS (also referred to as DISE�OS elsewhere in the log). Could you try changing this folder name to something without special symbols?
I install visual studio 2017 because i think it’s “newer” than visual studio 2015, but unreal still not let me pack or lauch my project!
I found another bug when my driver update notice me that 2 files of visual studio 2015 extremely old, need to be update, but when i let the driver update download the update, it can’t update those files!
I really don’t understand! please help
Hello jackbanner,
As this is an old question, it would be best if you could create a new post for your issue. When you do so, please include any error messages you’re receiving as well as your packaging logs. We’ll need this information to be able to help you.
