QUESTION: Your computer has a Windows 8 operating system and you're wondering if it's compatible with AutoCAD 2013.
ANSWER: AutoCAD is not a supported product for Windows 8 at this time, which means it has not been thoroughly tested. While some users have gotten AutoCAD to work on their Windows 8 system, there is no guarantee that the systems are compatible.
Please note that the educational version of AutoCAD is the same program as the regular version, it just has an educational license and should watermark files.
