Tried opening AutoCAD 2012 the other day and it went smoothly till 'checking licence' then it froze completely.
Went and downloaded 2013 and the same issue is happening!
After searching for similar threads by other people I tried some of the 'solutions' they advised...
My UAC is set the lowest possible and I'm set as the Admin on my system/ opening as Admin also. Yet it's still the same.
I'm running the program on Parallels if that makes any difference with a student licence. (I also tried the free trial and the same problem is happening).
I assume it's something on my end which is causing the problem but have no idea what!
Any help or advice would be great as I just want to get using it for my work!
