[WinError 193] %1 is not a valid Win32 application

[snippsat]

I use a 32bit eclipse with PyDev plugin
I have python 3.5 (32 bits)
Windows 7

When say python 3.5 (32 bits) is this trough anaconda?

File "C:\Users\Joan\Anaconda3\lib\ctypes\__init__.py", line 347, in __init__

Error:
OSError: [WinError 193] %1 is not a valid Win32 application

The error message is because you mixing are 32-bit and 64-bit.
