Die Ordnungszahl 63 wurde in der DLL “libexpat.dll” nicht gefunden

Question

I have a Python 2.5 program with code at

https://www.dropbox.com/s/wh1sgpsd248x85m/PopGen.zip

When I execute this program (python -m gui.mainwindow), I get the error message "Die Ordnungszahl 63 wurde in der DLL "libexpat.dll" nicht gefunden." (sorry, I don't know how to translate "Ordnungszahl" to English, literal translation - "ordering number").

When I look at the output of the program, I see the error

Error occurred importing qgis; no mapping support will be provided. Error message- DLL load failed with error code 182

This program makes use of the Quantum GIS (qgis) package, which is installed and the path with the DLL is included.

One possible cause of the problem is that there is another, older version of libexpat.dll in system32. But this isn't the case on my machine.

How can I solve this problem?

Answer 1

Thanks all for the help. Installing a different version of QGIS solved the problem.

Answer 2

It looks like the issue is an incompatible/ old version of libexpat.dll or in my case, no copy of it at all. I cheated and downloaded a copy of the DLL to the relevant Windows system folder.
