I am using AC14 INT (32-bit) on a MacBook Pro 17" late 2007 model, with Snow Leopard.
I have been using ArchiCAD since the days of AC7. In my experience, 7, 8 and 9 were the last really stable versions, of which 9 was, IMHO the best AC so far.
Since 10, things started going wrong and my AC got into a habit of crashing on me. Not so consistently as the latest two AC's, but it was just regular enough to become noticeable. The problem I have with 14 is not only does it crash regularly and unpredictably, it is SLOW.
But that is not the worst of all: I am the only user of Archicad in a company of 1000+ employees who are very loyal Revit / AutoCAD users. Because I have always believed in the product, I have kept up my service agreement with my local AC reseller, and paid for it myself. Not only that, everybody in our office knows that I am an avid supporter of ArchiCAD. What should I do when I am asked to give a demo or something to show AC's capabilities?:oops:
BTW, for the benefit of the users of older AC versions out there who are thinking of upgrading to 14: I have tried it on Win 7 32 AND 64-bit and AC either does not install (32-bit) properly, or it does not run at all (64-bit). And I tried all the help on the Archicad Wiki as well as my local AC guy. NO LUCK.
I am now working in AC12 and I have had to forego the new enhancements in AC14 as a result, but at least I can work longer that 10 minutes without AC crashing on me. I'm just beginning to wonder if I should not cancel that maintenance agreement.... at least until there is a stable version available.????
