I'm looking at the same problem. Do you know if it will work with 11.5 that dosen't use a dongle?
As for the reason I'm useing old software on a new machine, the museum I work for received Google Sketchup Pro for free and can't afford a newer VectorWorks for me so sad I know, don't everyone cry at once...
I just want to be able to open some of my old files time to time.
