Installation overview

RimuSDR, RimuDAX, and RimuCAT are distributed as .deb packages, RPM packages, and AppImages. Download them from the Downloads page, then follow the guide for your package format.

RimuSDR is also available as a fully supported Windows client; RimuDAX and RimuCAT remain Linux‑only.

The .deb packages and AppImages need glibc 2.38 or later

Every distribution listed below meets this. Older releases, such as Debian 12 (Bookworm) and Raspberry Pi OS Bookworm, ship glibc 2.36 and cannot run these builds.

RPM packages are built separately for each distribution release, so this limit does not apply to them.

To check your version, run ldd --version.

Package formats

Four formats are available. Native packages are preferred, because the system package manager handles dependencies and desktop integration.

  • Debian, Ubuntu and Raspberry Pi

    Native .deb packages with full desktop integration.

    Supported on Ubuntu 24.04 LTS and newer, Linux Mint 22.2+, Debian 13+, Pop!_OS 24.04+, Zorin Core 18+, and Raspberry Pi OS (64-bit) based on Debian 13 (Trixie).

    Available for amd64, arm64 and rpi. The arm64 and rpi packages are different builds for different hardware, so check which one you need before you download.

    Install .deb packages

  • Fedora and Rocky Linux

    Native RPM packages with full desktop integration. Download the build that matches your distribution release, for example fc43 for Fedora 43 or el9 for Rocky 9.

    Supported on Fedora 43 and 44, and Rocky Linux 9 and 10. Available for x86_64 only.

    Install RPM packages

  • AppImage

    A portable format that runs on most distributions without installation. There is no desktop integration, and updates are manual. AppImages need the FUSE 2 runtime library, which recent distributions do not install by default.

    Available for x86_64 and aarch64. Not available for Raspberry Pi.

    Run the AppImages

  • Windows

    RimuSDR is a fully supported Windows client with all core radio features available. Companion tools RimuDAX and RimuCAT are Linux-only, so DAX audio and CAT control are not provided on Windows.

    Available for 64-bit Windows only.

    Install on Windows

Components

Component Purpose Platforms Install order
RimuSDR Core application Linux, Windows First
RimuDAX Digital Audio eXchange - virtual audio channels Linux only After RimuSDR
RimuCAT Computer Aided Transceiver - virtual serial ports Linux only After RimuSDR

The packages do not depend on each other, so this order is a recommendation rather than a requirement.

Package file names

Downloads are named for their component, version, and target:

rimusdr_<version>_amd64.deb                 # Debian, Ubuntu, Intel and AMD
rimusdr_<version>_arm64.deb                 # Debian-based ARM64, not Raspberry Pi OS
rimusdr_<version>_rpi.deb                   # Raspberry Pi OS
rimusdr-<version>-1.<distro>.x86_64.rpm     # Fedora, Rocky
RimuSDR-<version>-x86_64.AppImage           # AppImage, Intel and AMD
RimuSDR-<version>-aarch64.AppImage          # AppImage, ARM64
RimuSDR-v<version>-Windows-x64-Setup.exe    # Windows 10 and 11

Substitute rimudax or rimucat for rimusdr to get the other two Linux components. Note that the Windows installer carries a v before the version number, where the Linux packages do not.

Next steps

After installation, activate your license. See the Activation Guide for instructions and troubleshooting.
