Install fastn on Windows

For Windows machine, there are three ways to install fastn.
  1. fastn through pre-built binary (Recommended)
  2. fastn using cargo
  3. fastn from source
Our Recommendation

We recommend you to install fastn through pre-built binary.

This is the preferred method as it only requires downloading the binary and installing it on your local system.

fastn is written using rust language, if you are familiar with it and want to use fastn for your project or for experimentation, you can do it with other two options, i.e, by installing it using cargo or by building the source.

Based on your machine and your choice of installation, you can select one of the following options:

fastn through pre-built binary

  • Download the executable from the Releases page

  • Click on latest release

  • Get the latest executable file for windows in the releases page, under Assets

  • Create a folder named FASTN in your C drive

  • Go to Settings and search Environment Variable

  • In the System Settings box, click Environment Variable

  • Double click on Path

  • Click on New button

  • Set a Path for FASTN in your machine’s Environment Variable
New Path
  • Click OK.

Installation of fastn is complete.

To verify, open command prompt and execute the command, fastn
If you see the Help text of the fastn command, it confirms that fastn is successfully installed.

Common errors to avoid

  • While renaming the file name make sure to write fastn and not fastn.exe
  • Check that your machine has the latest version of fastn
  • Make sure to start a fresh session of command prompt, to verify the installation
