如何在Windows 64位元中使用python呼叫32位元exe？

Question

I want to call a exe from python on a 64bit version of vista. I know to use subprocess, but all the 32bit apps are store in C:\\Program Files (x86)\\, and it doesn't like the spaces I believe. i have tried escape characters, doesn't fire, any ideas?

Answer 1

textEditorExecutablePath = 'C:\\Program Files (x86)\\Notepad2\\Notepad2.exe'
filepathToOpen = 'C:\\file.txt'
subprocess.Popen([textEditorExecutablePath, filepathToOpen])

Works for me. How are you calling Popen?
