Game runs fine in Editor but "Fatal Error" when starting packaged exe

Development Getting Started & Setup
1

I’ve narrowed it down to the plugin which is used for Spout. But even with a blank example, no actor or anything used from the plugin, only the plugin enabled, it will crash on startup.

But the standalone “run” in the editor works fine…

It is something about:
FCurlHttpManager::InitCurl()

Here is the end of the Log:

Anyone got any idea?

GitHub - leadedge/Spout2: A video frame sharing system for Microsoft Windows
the code and plugin needing to be built and binaries need to be copied into the plugin directory . the log above show fails to load in package games

Hello, thanks for the answer. But the plugin comes as a .zip with pre-built binaries. The binaries are also copied to the package output.

I’ve contacted the developer of the plugin and he could reproduce the error. They are working on a fix and will hopefully release a new version of the Off World Livestreaming Toolkit in the next few days.

Thanks for your help!
