Conda Update conda without admin privilge

hello to all, i’m not a developer but i need to setup andaconda for a user who need to update

being forced to install Anaconda for all users if i run the conda update with admin privilege the user is unable to run anaconda prompt correctly. The prompt is open it with an access denied error.

There is a way to fix it and in general to udpate conda for all the standard users?

Thanks in advance
