"OSError: [WinError 126] The specified module could not be found" while importing mxnet library

After installing below packages on Windows 8.1 CPU 64-bit using conda command: "conda install mxnet", I am getting error (OSError: [WinError 126] The specified module could not be found) while importing mxnet library.

Packages installed:

_mutex_mxnet: 0.0.40-mkl
libmxnet:     1.2.1-mkl_h0aaf724_1
mxnet:        1.2.1-h8cc8929_0
py-mxnet:     1.2.1-py36hcd68555_0

Also, popup window [OS error][1] [1]: https://i.stack.imgur.com/SKSm6.png appears while executing the import command with OS error description: "The program can't start because tiff.dll is missing from your computer.

Please note that tiff.dll file is already present in my folder "C:\Users\XX\AppData\Local\Continuum\anaconda3\pkgs\libtiff-4.0.9-hb8ad9f9_1\Library\bin" and have also tried re-installing the mxnet package but unfortunately problem is still not solved. Also, i already tried to searched similar issue on stackflow but couldn't find any relevant solution. Kindly help to resolve the issue.

PFB my code and error message.

Thanks for your response Sina. Yes, I already tried re-installing with pip but it doesn't help. However, I managed to solve the problem by overriding my environment path using below code. Thus, there seems to be some issue with retrieving environments path details which i already added correctly both in system as well as in account variables settings.

import os
os.environ["PATH"] += os.pathsep + 'C:/Users/XX/AppData/Local/Continuum/anaconda3/Library/mingw-w64/bin'
