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.
Hi @rootsmusic. Sorry to hear you’ve encountered issues with the installer.
Since you mentioned that base environment was not properly setup by the installer, even the uninstaller fails to recognize the installation directory as a conda directory which leads to the error messages you are seeing.
There are a couple of ways to tackle this and if you would be able to provide some more information we should be able to get through this.
Inside the installation directory you should be able to find a file install.log, can you share the file or the contents of it? A screenshot of the installation directory would also be helpful, I’m curious to see if any of the primary directories are missing from your installation.
Thanks, I was able to manually delete C:\ProgramData\anaconda3 and uninstall environments that were created outside the anaconda3 directory (which may have caused my original post’s problem). Then I reinstalled Anaconda Distribution.
