"The following modules are missing or built with a different engine version" with a new project
I was working on a project in Unreal Engine, and everything went fine until yesterday when I (as usual) switched to Visual Studio to edit some code, but when I switched back to UE window, I noticed that the compile button on the top disappeared. I restarted UE and tried opening my project but all I got was a message box with the following text:
If I click
Rebuilding the solution in Visual Studio doesn't help either.
I tried creating a new project in UE, but when I try to open it, it fails with the same error. I also reinstalled UE, but it also didn't help. What can I do to fix this problem?
I installed Unreal Engine 4.10.1 from Epic Games Launcher and I also use Visual Studio 2015 Community Edition which was installed when I first created a C++ project. I am able to open

It seems I finally fixed the problem when I added the
I ran into the same issue, and in the end what worked for me was right clicking on the uproject file, selecting "generate visual studio project files." From there I opened the newly created ProjectName.sln file with visual studio, and selected build. I let the project rebuild and then reopened, and voila, all was good again. Hope this helps someone else in my predicament.

I've had the same issue. I created a new project and copied all files from the earlier project to the new one except the files "saved" and "[project name].uproject". Then I started "[new project name].uproject" and it worked. Thank God! I'm so relieved.

I also had this problem but it was due to the fact I used a previous project to build off of. I needed to right click my .uproject file and edit the name like so:

You might wanna disable any plugins that your project currently have by editing your .uproject file with a notepad

Hi, in my case the issue was that my compilation was not creating the file UE4Editor-projectname.dll anymore.
This is because I was missing this line in \Source\MyProjectEditor.Target.cs:
Without this line the compilation succeed, but UE4Editor-projectname.dll is not created.

I had compiler errors when I last exited UE4/VS that seem to have been causing this issue. My solution was:
1) Open the Visual Studio Solution file in the project directory 2) Build the solution, and fix any compiler errors that appear 3) Once the build is complete, close VS and reopen the project from UE4

Had a similar issue with UE4Editor-UnreadEd.dll Deleted it from the UE4/engine/binaries/win64 folder and then compiled the UE4 project in VS and it rebuilt the dll and its fine now.
The initial cause was a power outage in the middle of a full rebuild. You might also want to compile your game project again just to be sure its up to date after that. If its another file thats causing the error for you, try deleting it and recompiling. (make a backup of it just in case)
