How to fix the error: there is an instance of Anaconda Navigator already running

On Windows

To resolve the error “there is an instance of Anaconda Navigator already running” on Windows, one solution is to locate and terminate the ‘pythonw’ process that is causing the issue. This can be done by following these steps:

1. Open a command prompt window with administrator privileges.
2. Use the command “tasklist | findstr “pythonw”” to locate the process ID (pid) of the ‘pythonw’ process.
3. Use the command “taskkill /f /pid <pid>” to terminate the identified process. This should resolve the issue and allow you to successfully launch Anaconda Navigator.

On Ubuntu 

the solution is to first use the command “killall Anaconda-Navigator” in the anaconda prompt to end the current running instance. Then, use the command “anaconda-navigator –reset” to reset the navigator and launch a new instance.
