Gum is an open source project so you can run it from source instead of running the pre-compiled project.
Download the source file from GitHub
If you downloaded the .zip file from the GitHub main page, unzip the file
If you downloaded the file through a Git client, be sure to be on the master
branch
Locate the Gum.sln file
If you downloaded the .zip, it is in the root folder of the zip
If you cloned the repository, it is at the root of the Gum folder
Double-click it to open Visual Studio, or open Visual Studio and load the .sln
Run the build configuration in "x86". The build configuration may default to "Mixed Platforms". If you do not change it Gum will not compile.
If your project depends on plugins, be sure to build solution, rather than pressing F5. This guarantees that all plugins are built and copied correctly.
