Original message:

After having dependency issues, I decided to delete and re-install anaconda3. I followed the instructions here (full uninstall --> simple remove - I am on Windows 10). In add or remove programs, I uninstalled both anaconda 3 and then Python 3 (I had installed python 3 externally to conda - I now know this was a terrible idea). I also uninstalled Python Launcher. I now want to re-install anaconda 3, but the anaconda 3 directory is still on my computer (C:\ANACONDA3 - it is 1.62 GB).

I am not sure why it was not removed - is it safe to simply delete it? I suspect that having two copies of Anaconda3 hanging around would be even worse than having multiple Python versions, so would like to be sure before I do anything.

Thanks!
Tim

Removing the ANACONDA3 folder is generally safe as conda installs isolated environments to your system

To ensure conda is completely removed from your system, you will need to make sure its removed from your PATH environment variables

To do so, follow these steps:

1. right-click on the Computer or This PC icon on the desktop and select Properties
2. Advanced system settings link which should appear on the left-hand side.
3. System Properties > Advanced > Environment Variables
   
4. Delete any conda related Variable:Value pair

If OP still runs into issue with anaconda installation, you can choose to install a minimal version via MiniForge for the community version replacement of Anaconda, the minimal installer skips packages which come with Anaconda.

After installation, run:

conda create -n firstEnv python=3.11 ipython to install python 3.11

• replace firstEnv with your environment name and 3.11 to desired python version

And install necessary packages via pip install and conda install

Happy coding!
