Windows: run the current-user installer, then open Proteonator from Start. Uninstall through Windows Apps. The installer is unsigned.
macOS: choose the disk image for your processor, open it, then drag Proteonator into Applications. Choose Apple menu > About This Mac to identify an Apple chip or Intel processor. The application has an ad-hoc signature and is not signed with an Apple Developer ID or notarized. macOS may block first opening. If you trust the source and have checked the checksum, follow Apple’s instructions for opening an app from an unidentified developer. The recorded Gatekeeper assessment rejected the application; signature integrity does not establish Gatekeeper approval. To update, quit the app and replace the copy in Applications. To uninstall, move that copy to Trash; projects and personal settings remain.
Ubuntu: download the .deb, open a terminal in its folder and run:
sudo apt install ./Proteonator-1.2.1-linux-x64.debOpen Proteonator from the applications menu, or run proteonator. The installer registers .proteonator projects and resolves desktop-library dependencies. Use the same command with the new package to update. Remove the application with sudo apt remove proteonator; projects and personal settings remain. Administrator permission is needed to install or remove the system package, not to run the application. Keep the normal application sandbox enabled. The Debian package uses Ubuntu desktop libraries; installing missing system libraries requires access to your configured apt repositories. Scientific work and saved projects run offline after installation.
Intel Mac verification covers macOS 15. macOS 26 on Intel is outside the release-verified scope.
Each package includes the scientific runtime and offline guide. Verify the SHA-256 checksums and save important projects before updating. Other systems and architectures are not verified. Native package tests do not establish Apple Gatekeeper approval or manual screen-reader compatibility.
See the platform verification record for the test scope, native workspace screenshots and graphics/accessibility limitations.
