Impossible to install any extensions

[eltitano]

Describe the bug

You cannot install extensions. Some registry entry is missing:
path = os.path.normpath(get_win_folder("CSIDL_COMMON_APPDATA"))
FileNotFoundError: [WinError 2]

Seems to be Python related.

Related command

az extension add --name XY, i.e. az extension add --name azure-iot

Errors

directory, _ = winreg.QueryValueEx(key, shell_folder_name)

Issue script & Debug output

directory, _ = winreg.QueryValueEx(key, shell_folder_name)

Expected behavior

az extension add --name azure-iot -> SUCCESS

What's the output of this in powershell?

cd "C:\Program Files\Microsoft SDKs\Azure\CLI2"
./python.exe -m site 

If you see extra folders other than this, then the Python you installed is interfering with CLI's bundled Python.
As a workaround, rename the extra folders during extension installation and revert it afterward.

sys.path = [
    'C:\\Program Files\\Microsoft SDKs\\Azure\\CLI2',
    'C:\\Program Files\\Microsoft SDKs\\Azure\\CLI2\\python311.zip',
    'C:\\Program Files\\Microsoft SDKs\\Azure\\CLI2\\Lib',
    'C:\\Program Files\\Microsoft SDKs\\Azure\\CLI2\\Lib\\site-packages',
    'C:\\Program Files\\Microsoft SDKs\\Azure\\CLI2\\Lib\\site-packages\\win32',
    'C:\\Program Files\\Microsoft SDKs\\Azure\\CLI2\\Lib\\site-packages\\win32\\lib',
    'C:\\Program Files\\Microsoft SDKs\\Azure\\CLI2\\Lib\\site-packages\\Pythonwin',
]
USER_BASE: 'C:\\Users\\hanglei\\AppData\\Roaming\\Python' (doesn't exist)
USER_SITE: 'C:\\Users\\hanglei\\AppData\\Roaming\\Python\\Python311\\site-packages' (doesn't exist)

key = winreg.OpenKey(winreg.HKEY_CURRENT_USER, r"Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders")

Code in Microsoft SDKs\Azure\CLI2\Lib\site-packages\pip_vendor\platformdirs\windows.py looks for registry keys only in current user tree but some of the keys like common appdata are located in local_machine tree.

Hang (@bebound) Your solution seems to work. Wish there was an easier way though

  Issue persists. Havent found a better solution than renaming directories.

Issue persists.

I have Miniconda installed... its python directories interfered and I had to rename
