Can't necessarily say it's the best way to do it but it seems to work (there's probably a way to delete any saved files from the temp directory when it's closed but at the same time I'm kind of hoping that windows knows how to manage cleaning that up...). I don't know of any way to directly create a process from an executable saved inside of the ct/cetrainer, so using the temp directory was necessary.
