activate.bat is not recognized as internal external command

I'm a beginner in machine learning so tried installing ANACONDA after the complete installation as the tutorial shows it doesn't ask me to install VS code.
That's not issue I can download it separately but I cant find the anaconda navigator.
when I open the anaconda prompt it shows activate.bat is not recognized as internal external command can you please help me if you know what is the problem.
I'm struggling in this issue from past 3 days... reinstalled countless time. Tried installing miniconda.
After installing still navigator doesn't appear.
But Promt works fine here so can run commands to install the navigator.
When the navigator gets installed I cant launch any apps like Jupyter notebook or spyder.
It shows Spyder Crashed.
Any help is appreciated.
Procedure that I followed.
1) Installed Anaconda
2) I did not find Navigator nor did the anaconda promt start it shows activate.bat is not recognized as internal external command.
3) So uninstalled anaconda and installed Miniconda in this anaconda prompt works fine but navigator wasnt there so i followed this post
Anaconda Installed but Cannot Launch Navigator
4) Then I could use the navigator and while I try to launch the spyder or the jupyter it throws error saying spyder crashed during last session
Can anyone help?

Installing Anaconda on Windows 10: Something went wrong during the installation, and conda cannot be found

I'm trying to install Anaconda on a Windows 10 laptop at work. For some reason, the installation always fails: I can see the Anaconda prompt, but no trace of Anaconda Navigator, Spyder, etc.
Every time I type where conda in the command prompt or the Anaconda prompt I always get the following message:
INFO: Could not find files for the given pattern(s).
And every time I try to use a conda command, I get:
'conda' is not recognized as an internal or external command,
operable program or batch file.
I know I messed up something in the installation (that I already tried a couple of times). I always kept the default options as I found in this DataCamp tutorial but I don't understand what is my mistake.
Any help? Thank you

Have you added conda to your path?
Conda command is not recognized on Windows 10
Once it is in your path, your OS will be able to know what you mean when you give it the 'conda' command.
where conda # windows
which conda # linux
should show you the path to the executable when you have set it up correctly.

if your installation path is something like: C:\Program Files\Anaconda2 or 3
please change it to: C:\Anaconda
and be sure that the check box in pic blow is checked.

Can't run Anaconda from command line (or anywhere else)

I am running Windows 10 with Anaconda 3. I attempted to get to the Anaconda Navigator through clicking on navigator app in Explorer (Anaconda3\pkgs\anaconda-navigator-1.8.7-py36_0) but that only brings up a flash of what I assume is the command window (because it's too fast to see) and then nothing happens.
I can use the Anaconda prompt and so I tried running navigator using 'anaconda-navigator' and it gives error line:
".....is not recognized as an internal or external command, operable program or batch file."
I tried typing 'jupyter notebook' into the command line but the message is:
Error executing Jupyter command 'notebook': [Errno 'jupyter-notebook' not found] 2
This has happened multiple times with me uninstalling and reinstalling Anaconda. How do I fix this as it seems to be a serious problem as almost nothing works?

For starters I would check the environment path.
if you go in the application folder, where the exe or run program is, can you start it?
Is there a bin folder? See if you can start Anaconda in debug mode.
this might help: http://anaconda-installer.readthedocs.io/en/latest/boot-options.html

I would first look to see whether anaconda-navigator and jupyter-notebook are installed in your environment through the command conda list at your anaconda prompt.
If they are missing just install them through conda install anaconda-navigator jupyter-notebook
Generally, i would execute the command conda install anaconda anaconda-navigator jupyter ipython just to be sure that no packages are missing from your environment.
Hope this helped. :)

To run anaconda-navigator:
$ source ~/anaconda3/bin/activate root
$ anaconda-navigator

Installing vscode, node, anaconda

My lecturer uploaded a youtube video explaining how to activate node and anaconda. I've installed node, anaconda (and vscode through the installation of the anaconda).
In the video, he says that we can check if the anaconda was installed properly by typing in the cmd
jupiter --version and then the version should be presented on the screen. I get the message:
'jupiter' is not recognized as an internal or external command, operable
program or batch file.
How can I fix this so that I could see the version? Thanks a lot.

pointed by #sini you need to check jupyter --version instead jupiter --version
if jupyter not installed
You need to install jupyter
python3 -m pip install jupyter
For windows get the help
you can verify if juypter packaged installed by pip freeze command
jupyter==1.0.0
jupyter-client==5.2.3
jupyter-console==5.2.0
jupyter-core==4.4.0 ....

Jupyter notebook and Anaconda Navigator does not show after installing Anaconda

After installing Anaconda3 I tried to search in my start menu for Anaconda Navigator but it just doesn't show. All I get when typing Anaconda in my start menu is Anaconda Prompt, I have tried to launch jupyter notebook from the Anaconda Prompt but it says that "jupyter n'est pas reconnu en tant que commande interne ou externe", and it's the same for Anaconda Navigator.
I want to add that I select the case that add Anaconda to the Path and I have installed miniconda too and I didn't have any error message while installing.

Yes I was having the same issues after installing Anaconda3-5.2.0-Windows-x86_64 on Windows 10. Though my previous install of Python 3.6.5 was working quite well.
A possible workaround - which worked for me beautifully - is to uninstall the Anaconda3-5.2.0 and install an old version.
Try Anaconda3-4.0.1 as I did from https://repo.continuum.io/archive/
While installing just accept all the defaults.
Confirm that the Navigator is installed from the Start Menu or launch from command prompt with this command:
anaconda-navigator
Once you are sure it is running - close and again from command prompt update to current version with:
conda update --all
Then:
conda update anaconda
You should now be good to go!

i solved my problem by del .condarc file. And restart Navigator. That's ok.

I tried an old version of Anaconda exactly Anaconda3-4.0.1 and it works. Now I have my Anaconda Navigator and can launch jupyter notebook.

This problem also happened to me under Ubuntu 16.04 LTS.
I solved my problem by changing my BASHRC file (~/.bashrc).
In this file, there is one line added by Anaconda installer:
export PATH="/home/mustafa1/anaconda3/bin:$PATH" # commented out by conda initialize
I just removed the # sign to make it work (of course I typed "source ~/.bashrc"), now I can see everything. I can use jupyter-notebook and anaconda-navigator.
Thus, my problem was a PATH issue. I think it is important where you install your anaconda.
