High Availability Add-on installation guide
To ensure the integrity and authenticity of the files that the High Availability Add-On (HAA) downloaded, UiPath® provides SHA-256 checksums for HAA packages. The sections that follow explain how to verify if your downloaded files have been corrupted or altered.
The following table lists the SHA-256 checksum values for each High Availability Add-On (HAA) installation package. Use these values to verify the integrity of your downloaded files before installation.
Compare the checksum generated on your system with the corresponding value in this table. If the values match, the file is verified and safe to use. If they do not match, download the file again from the official UiPath® source.

Checksums are available only for the following supported operating systems:
- RHEL8 - Red Hat Enterprise Linux 8
- RHEL9 - Red Hat Enterprise Linux 9
- Ubuntu Focal - Ubuntu 20.04 LTS
- Ubuntu Jammy - Ubuntu 22.04 LTS
The following sections include direct download links for the High Availability Add-On (HAA) installation packages. You can obtain either version-specific files for a particular HAA release or the latest available version for your operating system.
Each package includes the following components:
get-haa.sh— a helper script used to download and prepare the HAA installation package.haa-<version>.tar.gz— the compressed archive containing the HAA binaries.
Version-specific files
- https://download.uipath.com/haa/<version>/<OS>/get-haa.sh
- https://download.uipath.com/haa/<version>/<OS>/haa-<version>.tar.gz
The following list is an example for the version 2025.10.0 on RHEL8:
- https://download.uipath.com/haa/2025.10.0/Rhel8/get-haa.sh
- https://download.uipath.com/haa/2025.10.0/Rhel8/haa-2025.10.0.tar.gz
Latest version files
- https://download.uipath.com/haa/latest/<OS>/get-haa.sh
- https://download.uipath.com/haa/latest/<OS>/haa-latest.tar.gz
The following list is an example of the latest version on Ubuntu Jammy:
- https://download.uipath.com/haa/latest/UbuntuJammy/get-haa.sh
- https://download.uipath.com/haa/latest/UbuntuJammy/haa-latest.tar.gz
After you download the High Availability Add-On (HAA) installation files, verify their integrity to ensure that they have not been corrupted or compromised during download. UiPath® provides SHA-256 checksums for HAA packages so you can validate each file before installation.
Linux (bash)
- Open a terminal window.
- Navigate to the directory that contains your downloaded file using the following example:
cd /path/to/downloadscd /path/to/downloads - Calculate the SHA-256 checksum of the downloaded file:
sha256sum get-haa.shsha256sum get-haa.sh - Compare the output with the expected checksums.
The expected output format is:
a1b2c3d4e5f6... get-haa.sha1b2c3d4e5f6... get-haa.sh
If both checksums match, the integrity of the file is confirmed. If they do not match, delete the file and download it again from the official UiPath source.
macOS (bash)
shasum command instead of sha256sum.
- Open Terminal.
- Navigate to the directory that contains your downloaded file using the following example:
cd ~/Downloadscd ~/Downloads - Calculate the SHA-256 checksum:
shasum -a 256 get-haa.shshasum -a 256 get-haa.sh - Compare the output with the expected checksums.
The expected output format is:
a1b2c3d4e5f6... get-haa.sha1b2c3d4e5f6... get-haa.sh
If both checksums match, the integrity of the file is confirmed. If they do not match, delete the file and download it again from the official UiPath source.
Windows (PowerShell)
- Open PowerShell.
- Navigate to the folder containing the downloaded file using the following example:
cd "C:\Users\<YourName>\Downloads"cd "C:\Users\<YourName>\Downloads" - Compute the SHA-256 hash of the file:
Get-FileHash -Algorithm SHA256 "get-haa.sh"Get-FileHash -Algorithm SHA256 "get-haa.sh" - Compare the resulting hash value with the expected checksum.
The expected output format is:
Algorithm Hash Path
--------- ---- ----
SHA256 A1B2C3D4E5F6... get-haa.shAlgorithm Hash Path
--------- ---- ----
SHA256 A1B2C3D4E5F6... get-haa.shIf both checksums match, the integrity of the file is confirmed. If they do not match, delete the file and download it again from the official UiPath source.
