Floating point division by zero. / AfCore.dll Modul error / arcpy

Question

I have problem running my programm. i have wrote a Python programm to calculate Zonal Statistics for raster maps. Im receiving the following error:

Floating point division by zero.

and afterwards

Access violation at address 00007FFC90C687C1 in module 'AfCore.dll'. Read of address 0000000024FEB9E9.

I have tried several things and i have checked my paths and the whole code. I dont know where the error occurs from.

My Python code is in the appendix.

Thx for help

Zonal_Statistics_of Raster_test.py.zip

Okay i think i have the answer. The error occurs because i have no administration rights (Access violation). the afcore.dll file is in the windows folder and python is not able to get access to this file. I think i have to ask the administrator to run the programm with the required rights.

Thx Ducan for the suggestions

Right now it no longer runs. I checked everything and tried everything out. i had this error several times with different processes in the past. I have no clue. i wrote esri an email but they said because im student i have to ask a local competent. Is it possible to calculate Zonal Statistics over .shp Files or another data type. I think only raster are possible.i think i have to take some detours to get my results. im getting desperate:(

You can put scripts into the text of a question by simply copying it into it! Then use the "Use advanced editor" option and use the >> button to set the correct language of the code snippet. Personally if it is a big script I would attach it as a zip as you have done.

If your code sometimes runs OK then this suggest there is something else causing a problem, so its very difficult to answer this question.
