A recent post on py-dev (first link below) makes me think there is a way to fix this issue without changing PyInstaller, albeit with a bit of ctypes coding needed, at least until 3.8 is available. (I'm sensitive to this as I know our application will need to adapt, so I thought I'd toss this out here, since it seems related.)
https://mail.python.org/archives/list/python-...@python.org/message/R5RIBKDOH3J5ZBI22J3VHQWD4PEUTGWK/ >From the 3.8 porting notes: "DLL dependencies for extension modules and DLLs loaded with ctypes <https://docs.python.org/3.8/library/ctypes.html#module-ctypes> on Windows are now resolved more securely. Only the system paths, the directory containing the DLL or PYD file, and directories added with add_dll_directory() <https://docs.python.org/3.8/library/os.html#os.add_dll_directory> are searched for load-time dependencies. *Specifically, **PATH** and the current working directory are no longer used, and modifications to these will no longer have any effect on normal DLL resolution.* If your application relies on these mechanisms, you should check for add_dll_directory() <https://docs.python.org/3.8/library/os.html#os.add_dll_directory> and if it exists, use it to add your DLLs directory while loading your library. Note that Windows 7 users will need to ensure that Windows Update KB2533625 has been installed (this is also verified by the installer). (See bpo-36085 <https://bugs.python.org/issue36085>.)
