Hi Bo
First off, you may want to see were the temp files for Architect are on your computer. By default, this is how and were they are created after first install (your name should be in lieu of mine of course)

This is how you get there: Options/Preferences/Burning
Don’t ask me the technical reason why but Architect needs at least twice the amount of space needed when the temp files are created. So, with that in mind, you can change were you want your temp files (both of them) preferably on a separate drive.
Cheers !
