Before you install Positron, please review the prerequisites below to ensure your system is ready.\n\n## Prerequisites\n::: {.panel-tabset}\n\n### Windows\n\nIf you're using Windows, make sure you have the [latest Visual C++ Redistributable](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-microsoft-visual-c-redistributable-version) installed.\n\n### Python setup\nPositron works with [actively supported versions](https://devguide.python.org/versions/#versions) of Python, from 3.9 to 3.13.\n\nWe recommend [uv](https://docs.astral.sh/uv/guides/install-python/), or [pyenv](https://github.com/pyenv/pyenv) and [pyenv for Windows](https://github.com/pyenv-win/pyenv-win), for managing Python versions.\n\nPositron requires the [IPython kernel](https://pypi.org/project/ipykernel/) (version 6.19.1 or higher) to communicate with Python. By default, the IPython kernel is bundled with Positron for the CPython implementation (the standard Python implementation) and added to the [Python search path](https://docs.python.org/3/library/sys_path_init.html).\n\nIf you prefer finer control over your Python environment, set the [`python.useBundledIpykernel`](positron://settings/python.useBundledIpykernel) setting to false and install the IPython kernel manually\n\n::: callout-note\nIf you're using an implementation other than CPython, you'll need to install the IPython kernel manually.\n:::\n\n### R setup\n\nIf you plan to use R with Positron, ensure you have R 4.2 or higher installed. To install R, follow the instructions for your operating system at <https://cloud.r-project.org/>.\n\nAlternatively, if you'd like to have multiple R installations, [rig](https://github.com/r-lib/rig) is a great tool to manage this which works well with Positron.\n\nIf you're an R package developer, you will also want to make sure that you have the current versions of certain R packages, all of which had recent updates to make them work more smoothly in Positron. Run one of the code snippets below to ensure that you are up-to-date:\n\n``` r\n# if you're a pak person (we are!)\npak::pak(c(\"usethis\", \"cli\", \"crayon\", \"rlang\", \"roxygen2\", \"pkgload\"))\n\n# or using base R\ninstall.packages(c(\"usethis\", \"cli\", \"crayon\", \"rlang\", \"roxygen2\", \"pkgload\"))\n```\n\n::: callout-note\nIf you're a Windows user, note that Positron doesn't currently bundle [Rtools](https://cran.r-project.org/bin/windows/Rtools/). If you need Rtools for your package development or other work, you can either use the official guidance from CRAN on installing Rtools and putting it on the PATH, or alternatively, use [rig](https://github.com/r-lib/rig) to install and set up Rtools:\n\n```bash\nrig system rtools add\n```\n:::\n\n:::\n\n## Install Positron\n\nDownload the installer for your operating system from the button below and follow the standard installation process for your platform. You only need to install Positron once, as it [automatically updates](updating.qmd) to the latest version after installation.\n\n:::{.callout-important #privacy-policy}\n## Accept license agreement\n\nPlease review [Positron's license agreement](licensing.qmd) and [privacy policy](https://posit.co/about/privacy-policy/).
