I've been bumping into a bit of the problem exporting from CityEngine using the sticky in this thread. (My endpoint is Unity).
I'm running the 2012 City Advanced, and I have the same problem whether in a Mac or Windows environment. (I'm currently simply trying to export one of the sample projects they install for you, the Medieval 64bit city).
After configuring the offset points, and hitting export, I receive the following error, regardless of whether I am in Windows or Mac.
