Mambaforge

Mambaforge installs the mamba package manager with the following features pre-configured:

* [conda-forge](https://conda-forge.org/) set as the default (and only) channel.

* Packages in the base environment are obtained from the [conda-forge channel](https://anaconda.org/conda-forge).

You can provide parameters for the installation ([conda docs](https://conda.io/projects/conda/en/latest/user-guide/install/windows.html#installing-in-silent-mode)).

To have choco remember parameters on upgrade, be sure to set `choco feature enable -n=useRememberedArgumentsForUpgrades`.

* `/InstallationType:`[`AllUsers`|`JustMe`]

* Default: `AllUsers` (install for all users)

* `/RegisterPython:`[`0`|`1`]

* Default: `1` (register mambaforge python as the system's default)

* `/AddToPath:`[`0`|`1`]

* Default: `0` (do not add mambaforge directories to path)

* _Note: As of Mambaforge 4.12.0-0, you cannot add mambaforge to the PATH environment during an `AllUsers` installation.

This was done to address [a security exploit](https://nvd.nist.gov/vuln/detail/CVE-2022-26526)

([additional information](https://github.com/ContinuumIO/anaconda-issues/issues/12995#issuecomment-1188441961))._

* `/D:`(installation path)

* Default for `AllUsers`: `$toolsDir\mambaforge`

(`$toolsDir` is the path returned by chocolatey's `Get-ToolsLocation` function and defaults to `C:\tools`)

* Default for `JustMe`: `$Env:LOCALAPPDATA\mambaforge`

(`$Env:LOCALAPPDATA` is set by Windows and defaults to `C:\Users\{USERNAME}\AppData\Local`)

Example: `choco install mambaforge --params="'/InstallationType:JustMe /AddToPath:1'"`.
