Foundry is a new factory-management simulation game that utilizes the Paradox launcher for installing mods and as a general launchpad. However, the Paradox launcher causes specific Steam settings to stop working, such as "-popupwindow" which forces the game into borderless windowed mode. By disabling the launcher, users can enable these settings, as the game will bypass it. This may complicate adding mods, but deleting the launch option will restore the launcher as usual.
