Python addin_assistant error

[DongxiZheng]

Hello,

Has anyone encountered the same error as following while running the addin_assistant.exe wizard? Any idea on how to overcome?

Traceback (most recent call last):   File "addin_assistant.pyw", line 2, in <module>   File "addin_ui.pyc", line 5, in <module>   File "wx\__init__.pyc", line 45, in <module>   File "wx\_core.pyc", line 4, in <module>   File "wx\_core_.pyc", line 12, in <module>   File "wx\_core_.pyc", line 10, in __load ImportError: DLL load failed: %1 is not a valid Win32 application.

It sounds like you are running into the following bug:

NIM091620

"ImportError: DLL load failed: %1 is not a valid Win32 application." Error displays when ArcMap launches a 64-bit Integrated Development  Environment (IDE) as Editor or Debugger and the script imports arcpy.

Are you using a 64-bit IDE?

From the executable file itself you're getting the error? Try downloading it again and running it from a different location. Worst case scenario is to get wxPython for your current version and architecture of python and download the source of the addin wizard (click "Download ZIP" in the bottom of the right sidebar) and run it from your IDE/Python.exe.

I am on a 64-bit Windows 7 but not linking any IDE to ArcMap.

Yes. And re-downloading and re-positioning wouldn't help.

Thanks to you all for replying. Turned out that the problem was caused by my screwing up the Python installation folder. I repaired ArcGIS from CD and everything went back to normal.
