Anaconda Installed but Cannot Launch Navigator

Try to

source ~/anaconda3/bin/activate root
anaconda-navigator

https://github.com/ContinuumIO/anaconda-issues/issues/1580

How I solved this issue: 1. Be connected to the internet. 2. Open the Anaconda Prompt (looks like a regular command window). If you installed the .exe in your /name/user/ location you should be fine, if not navigate to it. Then start an environment.

conda info --envs

Then run

conda install -c anaconda anaconda-navigator

Press y when prompted (if prompted). It will being downloading the packages needed.

Then run your newly installed Anaconda Navigator

anaconda-navigator

It should start, and also appear in your regular windows 10 apps list.

activate the virtual env with command:

 conda activate base

run anacond anavigator

 anaconda-navigator 

Yet another option which worked in my case on Windows 10: Try uninstalling your previous installation, restart the system and run the installation again.

Make sure you don't start any programs before installing Anaconda. You will find the installation finishes without prompting any kind of errors.

Type in Anaconda in your Windows 10 Search bar. You will find Anaconda Prompt appear.

I figured out the reason as to why:

1-There seems to be no navigator icon

2-When conducting the above steps of running the "anaconda-navigator" command in prompt (whether cmd or Anaconda) it yields "anaconda navigator is not recognized as an internal or external command"

This was very frustrating to me as I'd installed the proper version multiple times with no avail.

To solve this problem :

• in the installation process, there will be an advanced options step with 2 selections one of which is unchecked (the top one). Make sure you check it which will add the navigator to the path of your machine variables.

it works :

export PATH=/home/yourUserName/anaconda3/bin:$PATH

after that run anaconda-navigator command. remember anaconda can't in Sudo mode, so don't use sudo at all.

I faced the same problem on Windows 10. As soon as I cleared my Path variable from edit environment variables option, the icon started to appear. It was occurring because I had previously installed python 3.6.1 on my computer and added it to my path variable as C:\Python36;C:\Python36\DLL; and so on. There isn't any need to uninstall Anaconda Navigator and start from scratch if you have correctly followed the steps mentioned at the documentation for it.

Try restarting the system! You will be able to find the navigator once you restart the system after installation.

Tried all solutions here but these 2 steps solved the issue:

1) manual update of open-ssl from here: https://slproweb.com/products/Win32OpenSSL.html
2) update OpenSSL using conda update openssl command in the Anaconda Prompt

solved the issue!

Make sure to run the installer as admin

In my case (Windows 11) it was a permission problem. Make sure to run the installer as administrator. You can check this by modification of the path in the installer process.

Further steps to handle the problem:

1. Uninstall your actual anaconda version.

2. Delete old Data found in:

   C:\Users\YourUsername\AppData\Roaming

   C:\Users\YourUsername

   • (In my case it was called .anaconda and .conda folder)

3. Restart PC

4. Install Anaconda as admin

Download and install Miniconda first from this link and later on download and install Anaconda. Then you will be able to see the navigator in your all programs list in the start menu. I hope this will help you. Let me know in case of any concerns.

You might not be in a anaconda environment

Below is a link how to activate the environment from the official documentation

On Windows, in your Anaconda Prompt, run activate myenv

https://conda.io/docs/user-guide/tasks/manage-environments.html#activating-an-environment

And then run the anaconda navigator from the anaconda prompt by entering the command anaconda-navigator

I had a similar issue today where only the prompt was available after installation. Finally solved this by un-installing my regular python installation and then install anaconda(anaconda 3 v5.2.0, with python 3.6).

I also have the issue on windows when i am unable to find the anaconda-navigator in start menu. First you have to check anaconda-navigator.exe file in your anaconda folder if this file is present it means you have installed it properly otherwise there is some problem and you have to reinstall it.

Before reinstalling this points to be noticed 1) You have to uninstall all previous python folder 2) Check you environment variable and clear all previous python path

After this install anaconda your problem will be resolved if not tell me the full error i will try to solve it

Uninstall your Anaconda, delete the folder where it was. Then reinstall it.

100% Solved. While Installing make sure you are connected to Internet. If already installed anaconda, open the anaconda command prompt and type following command:

conda install -c anaconda anaconda-navigator
(internet connection is required)

Note: In some cases restarting may solve the issue of navigator.

This is what I did

• Reinstall anacoda with ticked first check box
• Remember to Restart

I have that error an the solution was to install the Win64 OpenSSL.

In my case; it was available in the anaconda folder in "All App" from main menu

For people from Brazil

There is a security software called Warsaw (used for home banking) that must be uninstalled! After you can install it back again.

After thousand times trying, installing, uninstalling, cleanning-up the regedit that finally solved the problem.

First Run This Command

conda config --set auto_activate_base True

Then Run This Command

anaconda-navigator.

Turn off your internet connection, then open your terminal and type anaconda-navigator or type anaconda prompt in the search bar and double click on the anaconda prompt.

If anaconda is opened, then you can turn on your Wi-Fi.

I'm also faced with this issue. When I checked conda --version got a command not recognized error. Then I set the environmental variables as in https://stackoverflow.com/a/61372328/13370201. After that run anaconda navigator command. Then it started to initializing anaconda navigator.This tutorial also help for me.

I faced the same problem in Solus Baidge but I solved by activating the conda environment.

First activate

conda activate

Then run the navigator

anaconda-navigator

The followng command solved my issue.

pip install --upgrade pywin32==228

On windows 10, I faced the same error - only Anaconda Prompt was showing in the startup menu. What I did is i re-installed Anaconda and selected install for all users of the pc (in my initial installation I have installed only for current user).

What finally worked for me was:

1. Uninstalling Anaconda
2. Deleting all files that has "conda" in them - most of them should be located in: C:\Users\Admin
3. Delete especially the "condarc" file.
4. Reboot
5. Installed 32-bit installer (even though my system is 64-bit) and reboot

Finally worked. I have not yet re-tried with 64-bit installer, since I have a time critical project, but will do when again I have spare time.

P.S. what broke Anaconda for me was a blue screen I got while updating Anaconda. I guess it did not clear all old files and this broke the new installs.

I too faced a similar issue when I was not able to find the Anaconda Navigator Desktop app in the start menu. But do not worry , Go to start Menu and Type Anaconda Navigator. Now within the apps menu you will find anaconda navigator with its icon. Click on that. After clicking you will find a command prompt dialog opened and a .exe file runs on your machine. Wait till it completes.

The Anaconda Navigator app opens on your machine.

• From the Start menu select Anaconda Prompt. type anaconda-navigator.
• If Anaconda is installed properly, Anaconda Navigator will open.
