Conda and Anaconda errors when installing a package (pythonOCC)

Question

I am trying to install pythonOCC. Their website says in order to download use conda/anaconda. Instructions are here: http://www.pythonocc.org/download/

Specifically it says to type this command:

$ conda install -c conda-forge -c dlr-sc -c pythonocc -c oce pythonocc-core==0.18.1

First, i installed conda.

When i tried to pass the directory of the installation to my %PATH%, i saw that the conda executable was not named conda.exe, but rather _conda.exe.

Therefore to start it from the command line, i would type _conda, which is different from what the instruction say.

Then i typed the previous command (replacing conda with _conda). I got this:

NoBaseEnvironmentError: This conda installation has no default base environment.
 Use
'conda create' to create new environments and 'conda activate' to activate environments.

I typed _conda activate and i got this:

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your invocation to 'CALL conda.bat activate'.

To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - cmd.exe
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'.

The i typed _conda init and this is what i got:

C:\Users\User1>_conda init

Operation failed.

I then uninstalled conda and downloaded anaconda3, for which the exact same thing happened.

So, my question is, how to use either conda or anaconda, in order to download and install pythonOCC, in order to be used in python programs?

Have you tried running `conda init` as the error message suggests? — Garam Lee, Aug 20 '20 at 11:21
Oops, i forgot to add that into the question. I edited the question. — user1584421, Aug 20 '20 at 11:53
I run them on cmd.exe. I have installed/uninstalled both conda and anaconda so many times so i only go for cmd since it is a constant. — user1584421, Aug 20 '20 at 21:31
I believe that any commands that have to do with anaconda have to be run on Anaconda prompt — Garam Lee, Aug 21 '20 at 04:17
Tried in both anaconda cmd and anaconda powershell, running both as admin as well, and still the problem remains. — user1584421, Aug 21 '20 at 10:16
Is the error for `conda init` in anaconda prompt identical to the one in the post? — Garam Lee, Aug 21 '20 at 10:20

_When i tried to pass the directory of the installation to my %PATH%_ What do you mean by that? — AMC, Aug 22 '20 at 00:01
@AMC I included the directory of the installatin to the %PATH% environment variable. — user1584421, Aug 24 '20 at 08:58
I believe doing so is discouraged. It might be worth removing any changes you made, and trying with a clean install of Conda. — AMC, Aug 28 '20 at 11:13
I have installed Conda/Anaconda so many times while trying this. — user1584421, Aug 28 '20 at 11:44
