UE4 Launcher and Compiled engine from source

Hey, I’m experiencing an issue but I’m not sure what the source from the problem is. I also have a temporary work around, but I want to check on you guys if this is a known bug or if this is an issue on my end (installation).
So I’ve recently bought my UE4 subscription (when v1.1.0 was released). Because I wanted full access to the source code I downloaded the UE4 from the GitHub repository and compiled and installed it using the provided documentation. During the first boot I was instructed to install the Launcher. I downloaded the launcher and installed it in a different folder.

Now, when I download an example project from the marketplace the launcher tells me I don’t have the correct version of the engine installed. When I want to update my Engine via the launcher it gets stuck on 67%. When I look at the logs (cannot post them at the moment of writing) I gives me an error regarding a font file. I tried several solutions (the QFE2 and $moveMarked) but none solved the issue. But the funny part is, I have the most recent version of the Engine. My work around at the moment: download the sample, make a solution of it, recompile the project and run it from Visual Studio.

So basically it isn’t a real issue for me at the moment, but I wonder if this issue is because the Launcher is installed in a different folder. Or if this is a common fact? :slight_smile:

Thanks in advance and sorry for the wall of text :slight_smile:

Hey there! Right, so I ignored the issue so far but while migrating yesterday I took some time to track down the issue. So I figured out what was wrong with my installation. Though I guess a small bug caused the problem.
So after building the engine from the source code I wanted to add some samples. To do this I had to install the Launcher. After installing the launcher I wasn’t able to upgrade the engine. The problem was that the Launcher was installed in the wrong folder. Apparently it HAS to be installed in …/UnrealEngine/ so it can track the necessary files.

Bug Report Now after tracking the small issue by re installing the Launcher I found out that I could not set the directory path for the installation. So I had to manually copy/paste the folder into my engine folder. Maybe this isn’t an issue when installing the engine via download, but when you build the engine in an own folder, the option isn’t available.
Can someone confirm this bug?

Thx and I hope this can be useful for some people :wink:

Hi TheGoozah,

I have tried to reproduce this issue, and have not been successful so far. I did want to clarify one thing that confused me a little bit. Are you trying to use the Launcher to update the Editor that you compiled from source code? If so, that most likely will not work. The Launcher is intended to install and update a binary version of the Editor. To update a version that was compiled from source code, you would need to download the new version of the source code and merge it into your existing source code (or save it in a separate location if you prefer), then re-compile your Editor.
