Hi Guys -
Trying to clean up this question and give a firm answer here. If you are getting this error please try the following steps:
First Try these steps to ensure that you have the correct GitHub version:
- First Uninstall and delete all your engine files. You should not have to remove any project files.
- Next got to Epic Games/Unreal Engine’s Release page on Git Hub, here
- Download the 4.2.1 Release files: Source Code.zip, Required 1of2.zip and Required 2of2.zip. If you need to compile in VS2012 OR have projects that rely on dependencies in VS2012 then you will also need to download the Optional.zip. (This will take a while.)
- Next unzip the files in the following order into the directory of your choice. (For me I use D:\GitHub\Unreal Engine.): Source Code, Required 1of2, Required 2of2, and [Optional if needed]. Merge Folders as you unzip (They will all have files that go into the Engine sub-directory, for instance.)
- Once fully unzipped, Double Click on Generate Project Files.bat and wait for the file to run.
- Once completed you should now see two solution files, double-click (open) the VS2013 solution file.
- In VS2013, Build UE4. (This will take a while.)
- Once the Build is complete, you should now have the UnrealEditor.exe in your Engine/Binaries/Win64 subdirectory.
If you are subscribed through Microsoft to Visual Studio make sure that it is up to date and you have the latest version of either Visual Studio 2012 or 2013.
In any case, ensure that your copy of Visual Studio is up to date and installed correctly. No errors or exceptions are being generated from just opening Visual Studio. If you think that you have an error, complete uninstall and then re-install your version of Visual Studio with all updates.
These steps should solve your issues. User Alucard123, took the nuclear option of re-install his system and it definitely fixed his issue, but I would not recommend that as anything but a last resort and even then.
Try these steps and if you are still having this particular issue please comment to the Question and I will begin looking at this again
Thank You,
