Yes; I found this one result too.
So I did a search to find out what this AESOP could be, there are several entries for Äsop and one for a university network called AESOP.
I installed it from a CD-copy and also tried to install it from my disks (more from my save disks than from the original), they are more or less all corrupted somehow, so I used the first two originals and the other two from two different save disks. At least I always get this error, even with the copies on my CD.
I wonder what "inheritance" means in this error, what inheritance? Did I buy the game to use it for 10 years and the time is out now?
It seems that every other file is ok, the installation itself is ok so far until this error appears when I try to start the game.
I doubt that there is a company left who would change my old disks for new ones... *sigh*
