[Installer] C:\ProgramData\anaconda3 is not a valid conda directory

Today, I installed the Anaconda Distribution for Windows (2025.12-2). It installed successfully, but it didn’t create a base environment. So I’m trying to uninstall it by following the documentation for “Control Panel uninstall”, but Anaconda3 Installer says after step #5: “C:\ProgramData\anaconda3 is not a valid conda directory. Please run the installer from a conda directory.” (Same error when I manually run Uninstall-Anaconda3.exe.)

I don’t know why that’s not a valid directory. From which “conda directory” am I supposed to run the installer in order to uninstall Anaconda Distribution? My OS is Windows 11 Pro 64-bit. Thanks.
