(I posted this question on stack overflow but I hope being more lucky here)
I am having hard time to effectively switch between 64bit Python and 32bit. 1- I followed steps described here (Using multiple Python engines (32Bit/64bit and 2.7/3.5) <https://stackoverflow.com/questions/33709391/using-multiple-python-engines-32bit-64bit-and-2-7-3-5> ) 2- I successfully got a 2nd channel Python 3.6 32bit on my Anaconda Navigator 3- When I start Spyder, it is still running on 64bit interpreter 4- I forced the interpreter to launch the 32bit from: "Tools-->Python Interpreter-->Use the following Interpreter" then I navigate to the 32bit python.exe file created by the 2nd channel Yet it is still running on 64bit (I confirmed on spyder menu Help --> About Spyder... as well as by typing python in anaconda prompt) I need the 32bit python to call some DLLs using ctypes. If I don't do that I get the following error message: OSError: [WinError 193] %1 is not a valid Win32 application I tried to load a different DLL (64bit) and I didn't have any issues If using pythonnet (clr), I am getting this error message: FileNotFoundException: Unable to find assembly Note: this post (PythonNet FileNotFoundException: Unable to find assembly <https://stackoverflow.com/questions/28840880/pythonnet-filenotfoundexception-unable-to-find-assembly/28856382>) reported similar issue using clr, but I can't find: Properties-->General-->Unblock Thanks for your help -- You received this message because you are subscribed to the Google Groups "spyder" group.
