Hello -

This week I uninstall and re-installed VS 2017 which put me on 1.5.3. Since then I have not been able to build UE source no matter what I try. All the modules fail to build with the following:

Win10
4.5.1 Source From Git
VS 2017 Community 1.5.3
I’ve tried the “1.5.3 patch” as well.

2017 isn’t supported with 4.15. I believe first support of it was 4.16.

3

2017 started with 4.15

Was able to duplicate this issue on another machine, builds fine in VS 1.5.0 but not 1.5.3.

Ahh it’s not supported out of the box with 4.15. You need to compile it with 2015, then switch it to 2017. This is an issue for a bit VS2017 Support is incomplete and still relies on previous versions. - Feedback for Unreal Engine team - Unreal Engine Forums
