[Windows] CondaError: Unable to create prefix directory

[tabit01]

On Windows 11, with full Anaconda latest version, have followed installation steps. I did choose Anaconda to be installed for all users. After setting env variables and restarting PC, the config process starts in VS Code, then fail:

CondaError: Unable to create prefix directory 'C:\ProgramData\anaconda3\envs\fabric-synapse-runtime-1-1'.
Check that you have sufficient permissions.

Why install Anaconda in C:\ProgramData, and for all users? Because my Windows user name has two space characters in it, and a previous attempt to install in C:\ failed.

I realize that this is more of an Anaconda issue, than with the extension itself, perhaps? Still trying my chances, in case someone related to the extension have some clues to trouble shooting. Can I for example install the environment manually running Powershell as admin?
