Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Technical Issues Setup Error with Physical Disc

I'm trying to install Original Sin using the disc that came with the Kickstarter Backer Edition, but when I run the setup executable it returns an error saying, "No language configured". I'm not given an opportunity to actually select a language to run the setup in. Is there an option I can change/add/rewrite in the autorun or setup .ini's to fix the issue?
