Same problem.
If you try building a new c++ project it will fail with crtdefs.h missing and corecrt.h missing. You will also get the same result from blueprint project add a c++ class.
Googling all the answers says to add paths to some option which doesn’t exist.
UE4 not been working for 2+ weeks for me now, I’ve re-installed VS2015 but goes to upgrade 3 so it fails again. UE4 is just not compatible with VS2015 any more.
Hey Starglider17,
If you are using 4.12.5, there shouldn’t be an issue with Visual Studio upgrade 3. If there is, please make a new Answer Hub post in Bug Reports and we can further assist you.
If you are using 4.11.2, there is a fix you can download. More information on that is available here.
If you are on a earlier version than 4.11.2, sadly there isn’t anything we can do. My best advice if you are on a version before 4.11.2, is to download Visual Studio Community 2013 instead of 2015. You can do that here
I have both 4.12.5 and 4.11.2, neither work.
I have asked before but got a link to a MSDN page which told me to add paths, I went on a google mission to find out where to do this, which resulted in 1 being obsoleted (file menu tools > properties), the other via the right click menu on top item when project is open and selecting properties but doesn’t have the stated options or list anything c++. Then another recommendation was to make a c++ blank app, compile it and then try ue4 again, no joy. So no idea. I have even removed VS2013 and VS2015 and re-installed, still no joy.
I will post again however.
Kyle: I was able to track the crash down to plugins being asked to load before modules they required were loading. I modified the loading phases of the modules and plugins and everything works for the whole team now; however, my question remains unanswered. Why would this only fail on some machines and not others? Is there any reason this cyclic dependency didn’t crash on other computers?
As I try and expand out to some designers this is becoming a problem for me. What does “modified loading phase” entail (I see the loading phase listed for the dlls)?
I know this is an old thread but I just recently had this problem myself when trying to launch my project. UE 4.9.2, VS 2015. The prompt for rebuild failed so I tried building it directly from VS instead. Build failed in VS with hundreds of errors. Turns out I forgot a class declaration for a component inside a header file. Once corrected, I was able to build and open my project just fine.
Try building via VS and see if any errors show up.
