Can't compile to Win32 version

Ch3shireCat · April 18, 2017, 7:14pm

I am stuck. I have clean empty project in Unreal Engine 4.15, even without Starter Content. When I have it without Visual Studio C++ project (no C++ classes included), it can be compiled to Win32 version. When I add any MyActor C++ class, I get this as an output:

I looked three times not to get Development Editor or Debug Editor build in Visual Studio - there were topics about that Editor is only in 64 bit. When I try to compile it in Visual Studio, I get this:

…and yeah, it happened I have to develop for 32bit Windows 7 platform. FML apparently. (for 64bit everything works)

Not really because it’s Windows 7, but thanks.

The editor itself can only be built for Win64. However, this might be handy for you: Compiling Game Projects | Unreal Engine Documentation

Derp, I linked to the wrong thing. Here is what I meant to link to: Compiling Game Projects | Unreal Engine Documentation

So your game project can be Win32. It’s just the editor itself that has a 64bit requirement.

I know it can. It just doesn’t want to, and I’m trying to figure out why.

Turns out that I had to reinstall - or really, update - my Visual Studio 2017 to be able to do this stuff. I don’t know really which step helped, so I can’t tell it in terms of working solution - I have installed multiple VS crossplatform tools (for x86 platforms), even CLANG (outside the Visual Studio), in the meantime I had even to re-download Epic Launcher and UE4.15 because somehow it was deleted from my installed programs. But it helped - now I am able to compile for Win32 platform.
