'How to solve [WinError 5] Access is denied in anaconda prompt

I have recently reset my laptop and installed Anaconda in it, and I tried to open JupyterLab but it gives me error

Error executing Jupyter command 'lab': [WinError 5] Access is denied

but it works fine when I try to open JUPYTER NOTEBOOK or try to open JUPYTER LAB with Anaconda as administrator.

I reinstalled Anaconda, and still it gives me the same error. Also it gives me the same error when I try to open JUPYTER LAB from Anaconda Navigator. Before resting my laptop it works fine for me, but now it's not. I tried to search my query on the web before asking here, but I did not get my answer.

I want to run JUPYTER LAB with normal Anaconda prompt

Additional details

My Anaconda is installed in C:\ProgramData (by default).
I didn't check the box “add to path” while installing Anaconda.

Finally, I found a way to get rid of this problem following are the steps

step1: open your anaconda navigator 
step2: click on jupyter lab setting option and then remove it
step2: Now open your anaconda prompt and type the following command "conda install -c conda-forge jupyterlab"

now try to open it

EDIT (Reason of the problem and solution)

I found out that if you have installed Anaconda for all users then you will face this issue (thanks to @Alok, who also pointed out this). So the best or easy way to solve this problem would be to reinstall this but for only the current user. see the below picture

But if you have any requirements to install for all users then in that case, you can

step1: run the terminal as an administrator
step2: type jupyter lab

Optional (Automating launching jupyter lab with shortcut)

If you are lazy like me and, want to automate this steps then you can create a batch file and assign a keyboard shortcut to it. Steps are as follows;

step1: open notepad and write "jupter lab" and save it as a `.bat` file
step2: right-click on that file and click on create shortcut.
step3: now open the properties of created shortcut file and in the "shortcut-key" section type any combination of keys you want to set
shortcut.
step4: click on "Advanced" and select "Run as administrator"

Now you can initiate jupyter lab directly by typing your shortcut key and giving "yes" permission to the prompt.

Hope this helps you ?

You can just run it with Python:

python -m jupyterlab

This should work from an Anaconda Prompt or even the command prompt (if it uses the Python in Anaconda).

Try to execute as an admin. Problem solved.

This solution is unsafe. When you execute a program with Admin this program has full permissions over the system.

The good solution is to create a new environment with your current system user (not root/admin). Activate this new environment and it would works

I had the similar problem and it is related to windows security.

In order to solve it, run AnnaConda Navigator using Run as administrator option. Once Navigator is loaded you can launch the jupyter lab without errors.

Solution 5:^[5]

The problem I had is that it installed the application in users/<your username>/anaconda3/. To solve this I simply manually moved the folder with its contents to c:/program files/.

Solution 6:^[6]

The error occurs due to, your Not running as Administrator , simply Restart Cmd/Shell with Administrative privileges. It will solve the issue.

p.s ~It solved for Me

The solutions above works... But if you don't want to do those steps. I have another workaround, which I have been following.

What is that?

Usually, you don't have error in opening jupyter notebook command.

I usually type the jupyter notebook in the path bar in the explorer to open the notebook from that path directly — but as we are having an error in jupyter lab, I was only able to open jupyter notebook from there.

The solution for that is that,

Just type jupyter notebook as usual in the command prompt or the path bar in explorer.
As soon as the browser opens automatically, change the url from:

http://localhost:8888/tree to ? http://localhost:8888/lab

Yes, just a one word change. tree ? lab and... Whoo! The jupyter lab is open right there you want it to be!

Solution 8:^[8]

This is a problem that I see happening for Anaconda 3 installs for all users on Windows. Default (for single user) install seems fine. The permissions are somehow messed up during install. The solution I found is: explorer > right click anaconda3 folder > properties > security > advanced > change permissions > check "replace all child permission entries..." > OK.

This will take a while. After that uninstalling and reinstalling Jupyter Lab worked well.

Solution 9:^[9]

I want to emphasize what was written only as a comment, because it is easier to find it as an answer than to browse all comments:

If you are using Windows and installed it for all users, you will get this error.

The easiest way is to reinstall Anaconda only for you.

Note: You may uninstall your previous (unsuccessful) installation (for all users) before reinstalling it for only one user (you). But it is possible to do it later, too.

Avoid running as Admin due to security concerns. The fastest way is to create a virtual environment and install it there. This is what I did and it did not require any reinstallation of Anaconda or running it as Admin.

in anaconda prompt:

conda create -n myenv python=3.9
conda activate myenv
conda install -c conda-forge jupyterlab
jupyter lab

the last line will launch the jupyter lab.

Solution 11:^[11]

What I did is to create a new environment in Anaconda Navigator. I had the default environment which was root, so I could launch applications only as root. In the Anaconda Navigator Home screen click on Environments -> Create. Here is the guide to create a new environment https://docs.anaconda.com/anaconda/navigator/tutorials/manage-environments/

Hope helps.

Solution 12:^[12]

the easiest way to solve such problem is to run the anaconda prompt as administrator and you open the Jupiter lab

Solution 13:^[13]

I ran into this problem 'Error executing Jupyter command 'lab': [WinError 5] Access is denied' a few times now. The fastest way to solve this issue is to run the anaconda prompt as an administrator.

Solution 14:^[14]

If Anaconda Admin version was installed, click on the Anaconda Icon with Shift + right mouse button and select "Run as Admin". This worked for me.
