Error when running UE4Editor.exe - the application was unable to start correctly (0xc000001d)

When i double click on the UE4Editor.exe it says “A problem caused the program to stop working. Please close the program.” and that window closes and a new one appears saying "The application was unable to start correctly (0xc000001d). Click OK to close the application. Is there any way to fix that?

Also I could not find the UnrealEngine Launcher folder in "C:\Users(YOURUSERNAME)\AppData\Local\ ".
So do you think it didn’t install properly?

Hi - see this thread here for details on fixing this issue:

It seems to be related to not having Service Pack 1 for Windows 7 OS.

I could not find the UnrealEngine Launcher folder in "C:\Users(YOURUSERNAME)\AppData\Local\ ". There is no such folder there.

Hi ,

Do you have an AppData folder in your C:\Users(You Username Here) folder? Or is it the Local folder that is missing? At what point is the structure not correct?

Thanks!

Well, sir. I do have the Local folder inside the App Data folder. But I just can’t find the Unreal folder inside it. I was searching for the log files. Do you think this is because I didn’t install Unreal Engine 4 in C drive( Local Disk c) . Should I re-install it to C drive ? How do i uninstall it?

                 Thanks.

Hi ,

You should not need to worry about the AppData information just yet. Let’s return to the original issue.

You say that this issue exists when you run UE4Editor.exe. Does the issue also occur when you run the Launcher (UnrealEngineLauncher.exe) and click on the Launch button?

Some general information about runtime errors is provided in the answers of this post:

Other users have reported your specific error message (0xc000001d) and have been able to resolve the issue by either installing Windows 7 Service Pack 1, or by installing the VS2013 Redistributable package: http://www.microsoft.com/en-us/download/details.aspx?id=40784

I recommend trying these solutions, and letting us know if the error is still occurring.

Cheers

alright sir, I’ll get windows 7 sp 1

It worked exactly like you said sir. I installed windows 7 service pack 1 and now my editor works perfectly. Thank you.

Hi ,

Just as a heads up if you had taken the time to read my reply instead of going into the thread and then not reading all the content there, you would have fixed this issue a lot earlier.

Thanks.
