E370: Could not load library python36.dll

[FR4N7Z]

Hello,
I am using the lasversion of vim with dynamic support of python 3.
When I run :version, Vim is looking for Python36.DLL.
Python3 is installed in C:\Program Files (x86)\Python36-32, the DLL is in this folder and this folder is in the PATH. But when I run :python3 print("Hello world"), it returns
E370: Could not load library python36.dll
E263: Sorry this command is disabled, the Python library could not be loaded.
Thank you.

What does :echo system('where python36.dll') show?

[FR4N7Z]

It say in French that it is impossible to find files for the model

[k-takata]

Then the PATH setting might be something wrong?
What does :echo $PATH show?

[FR4N7Z]

The path show C:\Program Files (x86)\Python36-32\ where is python36.dll.

@FR4N7Z If you try to run python on cmd.exe or powershell, does it start the python interpreter with some text like this?

Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:04:45) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

Second question: did you install the 32-bit Vim or 64-bit Vim? The bit must match between Vim and python's dll.

[FR4N7Z]

Yes it show a message like this.
And yes Vim is 32 bits.
Thank you.

That's very odd. If the dll is in any directory in $PATH, Vim should be able to find it. Just tested it myself too by moving the python36.dll to a random directory in $PATH then running :py3 print("hello") in gVim

My environment: Windows 8.1, Python 3.6.4 32-bit (user installation), gVim 8.0.1555 (installed using vim-win32-installer).

There's one more thing to try: run this in Vim (replace \path\to with your actual directory).

:let &pythonthreedll = 'C:\path\to\python36.dll'

[FR4N7Z]

That's work! I think this is a bug but your trick works. Thank you.

I had the same problem for some reason. This is the only solution I've found so far. Thanks a lot!!!
