Okay, I messed up something real good. A project cannot be restored in a traditional way (Checkout and Rebuild). This is only for a single project, others are working properly.
Someone had this before? Any ideas how I could rebuild it manually?

Try opening the Visual Studio solution and building the project from there. If that doesn’t work try clearing the derived files like this…
- Close Unreal and Visual Studio
- Delete the following folders: Binaries, Build, Intermediate, Saved
- Delete the Visual Studio or Xcode solution file (.sln or .xcodeproj)
- Re-open Unreal
Good luck!

Hmm, sounds like you may have some corruption. Can you go back to a previous commit of either yours or ours?

My bad. I was checking out with uncommitted changes. Those were making the project un-compilable. Maybe someone will learn from this. Thanks, Ben.

I had a similar issue, but mine wasn’t solved by rebuilding alone.
I made the mistake of letting VS update to a new version that was incompatible with Unreal 4.11
Unreal was notified of this issue and made a fix in 4.12.5 that resolved the issue.
- Install version 4.12.5 from the epic game launcher
- Clear out your temporary files
- You can right click on the .uproject file from the explorer and select “switch unreal engine version”
- Double click the uproject file to open and it should rebuild the .dll properly and open the editor

And I have given permission to that file that says I do not have rights to run this command.

I think the problem is that a few days ago I updated VS because it gave me a notification to update it, and so I did. I don’t know, just guessing. I think UE4 is not compatible with the new VS update I installed a few days ago. I’ve updated the UE4 as well, and still no luck.
Your help will be appreciated,
Thank You
If you open the solution in VS and compile what error do you get?

Sorry I missed that. Was this after doing something else like uninstalling VS 2015? or Upgrading engine?
I have VS 2017 installed and it works fine with UE 4.15.1 with Building Escape (the previous section in the course). I updated this before I try to create the Battle Tank project.
Not entirely sure, so it still compiles fine in 2015?

I’ve never had installed VS 2015
Try installing this

As well as running the VS installer and installing the Win8.1 SDK
