[python] Where does Anaconda Python install on Windows?

I installed Anaconda for Python 2.7 on my Windows machine and wanted to add the Anaconda interpreter to PyDev, but quick googling couldn't find the default place where Anaconda installed, and searching SO didn't turn up anything useful, so.

Where does Anaconda 4.0 install on Windows 7?

where conda

F:\Users\christos\Anaconda3\Library\bin\conda.bat

F:\Users\christos\Anaconda3\Scripts\conda.exe

F:\Users\christos\Anaconda3\condabin\conda.bat

F:\Users\christos\Anaconda3\Scripts\conda.exe --version

conda 4.6.11

this worked for me

If you installed as admin ( and meant for all users )

C:\ProgramData\Anaconda3\Scripts\anaconda.exe

If you install as a normal user

C:\Users\User-Name\AppData\Local\Continuum\Anaconda2\Scripts\anaconda.exe

Update May 2020, installed Anaconda 3 Individual Edition from https://www.anaconda.com/products/individual, chose 32-bit installer for Python 3.7, and installed with Default options.

Here is the directory where Anaconda was installed (C:\ProgramData\Anaconda3). Note ProgramData is a hidden folder not visible via Windows File Explorer.

And launching Anaconda command prompt from Start Menu>>Anaconda3 gives below command shell

"where anaconda" command gives below output C:\ProgramData\Anaconda3\Scripts\anaconda.exe and versions for anaconda, conda, python

Updated original question which was asked 3 years ago, and is relevant today as well in May 2020 as I had similar question/doubt when installing Anaconda recently.

With Anaconda prompt python is available, but on any other command window, python is an unknown program. Apparently Anaconda installation does not update the path for python executable.

This one is easy. When you start the installation, Anaconda asks "Destination Folder" as below screenshot. If you are not sure where did default installation go, double click setup file and see what anaconda offers as a default location.

You can search for "Anaconda prompt" in installed programs and run it.
When it opens, it shows the directory anaconda is working from.

As you can see c:\programdata\anaconda2 is my installed directory.
*side note: programdata folder is hidden in windows so you'll have to enter its path in the folder explorer to access it.

C:\Users\<Username>\AppData\Local\Continuum\anaconda2

For me this was the default installation directory on Windows 7. Found it via Rusy's answer

The given answers work if you're in a context where conda is in your PATH environment variable, e.g. if you set it up that way during installation, or if you're running the "Anaconda Prompt".

If that's not the case, e.g. if you're trying to locate conda for use in a script, you should be able to pick up its installation location by probing HKCU\Software\Python for available Python installations. For example:

>for /F "tokens=2,*" %a in ('reg query HKCU\Software\Python /f InstallPath /s /k /ve ^| findstr Default') do @echo %b
C:\Users\<username>\Miniconda3
C:\Users\<username>\Miniconda3

Open the Anaconda Prompt and type:

> where python

conda info will display information about the current install, including the active env location which is what you want.

Here's my output:

(base) C:\Users\USERNAME>conda info

If your shell/prompt complains that it cannot find the command, it likely means that you installed Anaconda without adding it to the PATH environment variable.

If that's the case find and open the Anaconda Prompt and do it from there.

Alternatively reinstall Anaconda choosing to add it to the PATH. Or add the variable manually.

Anaconda Prompt should be available in your Start Menu (Win) or Applications Menu (macos)
