DLL not found

[smestern]

Hello,

Apologies for the slow response! I have encountered this before, the ctypes library gets a bit finicky about where the DLL is packaged. I will look into this asap! Two quick questions:

• Did you install via PIP?
• What operating system are you using?

Hi,

No worries for the response, it is summer for everyone (and apparently this response never got sent, so I am even more guilty of it).

ctypes is indeed .. finicky, this is an understatement.

I tried under Windows, and I used pip indeed. Would another install route be easier? Would this even work under another OS than Windows?

Cheers and thanks for looking into it.

PIP and Windows are definitely the best options! I will keep trying to replicate the issue. Currently I have tested on python 3.7 on 64 bit windows, without much issue. It looks like in 3.8 the dll search mechanism has changed, will be looking into this asap!

Just to let you know that I tried on a different computer, using Python 3.7, and I got it to work. I will need to investigate some more. Let me know if you find something

But still impossible to get it to work on the lab computer... I am wondering if there is an hidden dependency, another DLL used by the CFS64.dll. That could trigger this error I think

I was unable to replicate the issue. However I tried pushing an update that may solve the issue for >3.8 issues entirely. I will dig further into the DLL! It does rely on a lot of legacy code that may be missing on the given computer.

@remi-pr @smestern I think I've solved this with #6. Rémi was right: CFS64.dll has a hidden dependency on MSCVR100.dll, which is part of the Visual Studio C++ 2010 Runtime. Once you install that, pyCEDFS should work as intended!

Thank you @a-hurst for the fix! I have pushed the changes accordingly to PyPi. Seems to be working flawlessly!

Great news. Thanks @a-hurst for the find! Thanks @smestern for the update. I will give this new version a try soon.
