I am in win11 Enterprise 23H2, OSbuild 22631.5472. I have a fresh installation of anaconda 2025.06, but could not get Anaconda Toolbox 4.20.0 installed. Neither from Anaconda Navigator nor from CLI.

The following are the full error messages from installing in command prompt:

Any help will be appreciated, especially from conda’s developers.

Hey @quan1, welcome to the Anaconda forum!

Having a look at this thread which appears to have similar errors.

Looks like there are two main issues that might be causing it:

  1. Permissions error which you might need some IT Approval to resolve
  2. Python version issue - create a new environment with python=3.10 and see if that helps.

Happy to jump on a call to try and help resolve, so drop me a DM on here if you would like additional support.

Thanks,
Jack
