# Intro & Downloads

## Downgrading

Beta versions may sometimes change your collection in a way that is not
compatible with older Anki versions. If you wish to switch back to an older
version, please go to the `File>Switch Profile` menu item, and click on
`Downgrade & Quit` in the current version first.

## Problems

If you run into any issues, please let us know on the
[beta testing section](https://forums.ankiweb.net/c/anki/beta-testing/13) of the user
forums.

## Packaged Builds

Betas are posted on [https://github.com/ankitects/anki/releases](https://github.com/ankitects/anki/releases).

## Via PyPI/pip

If you have a local Python 3.9+ installation, you can also install beta builds
directly with pip.

Anki will be installed in a local Python folder called 'pyenv'.

  <summary>Mac (both Intel/Apple), and Linux (x86\_64)</summary>

  ```
  $ python3 -m venv pyenv
  $ pyenv/bin/pip install --upgrade pip
  $ pyenv/bin/pip install --upgrade --pre 'aqt[qt6]'
  $ pyenv/bin/anki
  ```

  * Repeat the last step if you wish to start the same Anki version again.
  * Repeat the last two steps to update to the latest beta and start it.

<details>
  <summary>Linux (ARM)</summary>

  As there are no PyQt packages on PyPI for Linux/ARM, you will need to have your
  distro's PyQt5 packages already installed. Eg on Debian 12:

  ```
  $ sudo apt install python3-pyqt6.qt{quick,webengine,multimedia} python3-venv
  ```

  Or on Fedora:

  ```
  $ sudo dnf install python3-qt5-webengine
  ```

  Then run the following:

  ```
  $ python3 -m venv --system-site-packages pyenv
  $ pyenv/bin/pip install --upgrade pip
  $ pyenv/bin/pip install --upgrade --pre aqt
  $ pyenv/bin/anki
  ```

  * Repeat the last step if you wish to start the same Anki version again.
  * Repeat the last two steps to update to the latest beta and start it.

<details>
  <summary>Windows</summary>

  ```
  c:\> python -m venv \pyenv
  c:\> pyenv\scripts\pip install --upgrade pip
  c:\> pyenv\scripts\pip install --upgrade --pre aqt[qt6]
  c:\> pyenv\scripts\anki
  ```

  Repeat the last step if you wish to start the same Anki version again. Repeat
  the last two steps to update to the latest beta and start it.
