Pobierz dla WindowsWhere the file comes from and what to expect
We publish the installers in the project's GitHub repository - latest release, AGPL-3.0: github.com/matematicsolutions/patron/releases.
Check the file before you run it. Each release includes a CHECKSUMS.txt with SHA-256 sums. In PowerShell: Get-FileHash .\PATRON-Setup-Windows-EN.exe -Algorithm SHA256. If the sum differs from the published one, do not run the file. Download it again, and if it still differs, write to [email protected].
Windows will then show a SmartScreen warning, because the file has no publisher certificate yet. Click More info, then Run anyway. The certificate arrives in version 2.0.
Each edition is a separate installer with one interface and agent language. EU law (EUR-Lex, the compliance corpus) and other countries' connectors live in the Boutique - you download the file and attach it to the app when a matter calls for it.
Before you start the application for the first time, read the step-by-step manual: installation, connecting a model (your own key, or a local model with no network), creating your first matter, and the list of pitfalls that actually occur.
