Running 32-bit Python in 64-bit Windows 7 Enterprise. I am very much a Python noob. A .dll in c:\Windows\System32 that I need to access can't be found by ctypes.WinDLL(). Upon further investigation I have found that the file, along with many others, doesn't show up in an os.listdir() either. Within IDLE the files don't appear in the drop-down autocomplete list. I don't have this problem on either of the Windows XP machines I've tried it on, but in Win7 I see the same behavior in both 2.7 and 3.2.

Does the file exist at all? Does it have some specific properties? a "Hidden" flag?

Most likely, you are using a 32-bit Python on a 64-bit Windows. 32-bit programs can't access c:\windows\system32, as that will contain the 64-bit DLLs. Instead, access is redirected to c:\windows\syswow64. Please confirm whether or not this is the case here also.

Thanks for the suggestions. Since I can put the OEM-supplied DLL in another directory and everything works just fine, I'm not going to spend any more time on it. I assume that it's something to do with file permissions in Win7 that I don't have any inclination to delve into further. And I can always run it on my old laptop if I have to. === Jon

Closing the report as invalid then.
