System requirements
For a demo or trial installation, and to run the Breeze tutorials, any PC hardware is fine.
The Prediktera website lists system requirements and recommendations at Supported Hardware - Prediktera.
For the best performance a fast Intel CPU and enough RAM for your data is recommended. See Breeze log files and troubleshootingfor some information on how to evaluate memory usage.
Breeze does not take advantage of fast GPUs because the complex workflows are not well suited to GPU acceleration.

Installation
Breeze comes in the same installation package, regardless of the edition of Breeze you use, including the trial version, or if you are doing a Runtime installation.
You can only have one Breeze version installed on a PC at the same time. Running the installation program will replace any existing version. Learn more about upgrades in the next section.
After downloading Breeze, you find the installation program in the Downloads folder.
Start the installation, by opening the file Prediktera_Breeze_Windows_202x.x.x.exe).
The Breeze Setup Wizard starts. Follow the instructions on screen.
After clicking Next and accepting the license agreement you get to select the optional cameras to use for data acquisition.
If don’t have a camera or just want to run the tutorials, select No external camera.
Click Next again and select the destination folder to install to:
Click Install to complete the installation.
The installation program creates installation log files in the logs folder in the program folder (typically C:\Program Files\Prediktera\Breeze\log). Those can be shared with Prediktera support for troubleshooting installation issues.
There is also a Linux installation. It contains a README file with instructions.
Upgrading Breeze
If Breeze is already installed on a PC, running the installation will replace the previous version, and, if necessary, migrate settings in the workspace to the new version.
If you upgrade from an older major version of Breeze, such as 2024.2, the migrated settings will not be backwards compatible with the old version. This means you cannot roll back the upgrade unless you have a backup of the Workspace.
For this reason, it is a good practice to ensure you have a backup of the Workspace before you upgrade. Learn how to backup in Breeze system overview.
You can also create and switch to a new workspace in Breeze as described in Workspace guide, before upgrading. This ensures only the test workspace is migrated.
To revert back to an earlier version, install the older version (in this case, it is recommended to uninstall the newer version first).
Licensing activation
Breeze requires an activated license to run.
A free trial license can be easily obtained. Learn more in Free Trial - Prediktera
