Is this a personal or company device? Do you have write permissions to all folders?

Hi. This is my personal device and I have permission to all folders. I tried updating to the newer version from 2.6.1 and i uninstalled the older Pumas version from my system.

Please try to delete the `C:\Users\<YOUR_USERNAME>\.julia` folder as well as any Pumas related entries in you `settings.json` VS Code configuration file and then rerun the installer.

Could you please share the output from running `ls C:\Users\sutha\.julia\environments` in a PowerShell terminal?

You didn’t successfully delete the `.julia` folder. You can see that the time stamp for the `Pumas_v2.6.1` folder is from february. Please try to delete the `.julia` folder and then rerun the installation steps.

Hello. I followed the steps here to uninstall my prior Pumas version and reinstall 2.7.0. ( [Desktop Installation · Pumas](https://docs.pumas.ai/stable/platformdetails/desktop/) ). I’m getting the below error when trying to start a Julia REPL. Any suggestions would be greatly appreciated.

Can you restart your VSCode and open the Pumas extension. Then can you follow the steps to install 2.7 again (it will show that is already installed) and then you need to configure the VSCode settings globally when the popup shows up

It looks like there are some leftovers settings related to Pumas 2.6.1 in your `settings.json` file. Please open the file by selecting the “Open User Settings (JSON)” in the command palette, see below. Then please delete any entries related to Pumas/Julia and rerun the new installation steps.

Awesome - this worked. Incase it’s helpful for others, below is what my settings.json looked like. After deleting & saving I ran `Pumas: List Versions` from the Command Palette and chose Configure VS Code (Pumas 2.7.0 was already installed). All works now. Thanks for the help.

Hi, I am trying to uninstall the older version and install the new version of Pumas; however, I have encountered the following error messages when I was trying to run “Pumas: List versions” in the command palette. I am very new to Pumas and JuliaHub, so apologies if this is some very obvious mistakes on my end. Thank you for your help in advance.
