yes that was the problem. i had to edit the path to GStudio7 in my computer.

another issue ... you say in earlier posts that the wrapper covers around 75% of the engine commands. For my current project I need ent_blend and ent_animate. I tried and they dont seem to be there

>>> import a7
>>> help(a7.ent_blend)
Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
help(a7.ent_blend)
AttributeError: 'module' object has no attribute 'ent_blend'

I guess there are part of the 25% still not covered.
