Python3: Could not find "vcomp140.dll (or one of its dependencies)" while trying to import nltk

When I try to import nltk on Python 3.9.1 on Windows 10 Pro, I get the following error:

Traceback (most recent call last):

FileNotFoundError: Could not find module 'C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python39\lib\site-packages\sklearn\.libs\vcomp140.dll' (or one of its dependencies). Try using the full path with constructor syntax.

Any idea how to fix this? I've tried reinstalling ntlk (by typing pip install nltk), but it doesn't work. I've also tried pip install sklearn, no success. Even uninstalling nltk first and then reinstalling did not help, nor did restarting the computer after all this.

I can also tell that there is no subfolder (or file) called .libs (nor libs for that matter) in the C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python39\lib\site-packages\sklearn folder.

I've also tried to install Visual C++ from the link posted in an answer, but it does not work either as it says that it's already installed. Here's the log file, again my real username replaced with .

As @Rabindra suggests, the issue lies in missing Visual Studio C++ Redistributable binaries.

You can install them from the official link. They are dependency of many of the C++ libraries compiled on Windows that expose Python API (or python modules that are in fact interfacing into C++ libraries).
