Hi,

I am trying to compile Unreal Tournament 4 myself, so I can try to make modifications to it.

Unfortunately, after following all the steps on these pages:

[https://github.com/epicgames/unrealtournament](https://github.com/epicgames/unrealtournament)

> **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)**
>
> After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — https://unrealcommunity.wiki/! You will be able to find content from...

and selecting “Launch” from within the editor, I am getting this error:

![36079-error3.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/a/f/c/afc50ff151738afc807e0e01a63c6c2e0e15f341.png)

On my blog I have explained the steps taken: [Compiling Unreal Tournament 4 from GitHub source | Fancy Blog](http://www.fancyaddress.com/blog/c/compiling-unreal-tournament-4-from-github-source/)

Please tell me if I have missed any important steps, and explain how to fix this error.

Thanks!

Hi FakeTruth,

Since the AnswerHub is specifically geared towards the Unreal Engine 4 you’ll probably have better results posting this report on the [UT Forums.](https://forums.unrealtournament.com/)

Cheers,

TJ

Thanks TJ,

I did not realize the AnswerHub was not also for UT. I will try the UT forums.
