Windows · install and maintain the suite

One application to find and update the others.

Distinguish catalog, download, verification and installation; retain your projects and explicitly decide what to update.

Guide reviewed · 12 November 2026 · DiffAtOnce Studio 0.1.1 · Download and calculation times depend on data and hardware.

  1. Retain your work and download the official installer

    Save open projects and retain a backup. Download Studio 0.1.1 from the official Studio page; compare the published version, size and SHA256 before installation.

    Before continuing: The MSI files are not Authenticode-signed. A catalog signature does not remove Windows or SmartScreen warnings; do not disable protections.

  2. Open Studio and read catalog status

    Choose Español or English. Studio checks at startup and every four hours while open; Check for updates repeats the check. Read whether the catalog is verified, unavailable or rejected.

    Before continuing: Offline or rejected catalog does not mean every application is up to date. Never import a key proposed by the catalog itself.

  3. Find the application and distinguish its format

    Use search, filters, grid or list. Open Details for local and published versions, location, provenance and notes. Local portable is a copy you can open, not a managed MSI installation.

    Before continuing: Applications without an available MSI retain their official page; a card does not establish that an installer exists.

  4. Install Prime or ResinAtOnce with confirmation

    Select Install on the reviewed card. For a local MSI, select it through Open catalog / MSI; selecting a file does not install it. Studio checks MSI identity, version, size and SHA256 before starting Windows Installer.

    Before continuing: First MSI installation uses a fixed path separate from a portable copy and may need normal registration or activation. Credentials are not copied and projects are not recalculated.

  5. Update only closed applications

    Save and close the target application. Review the new version and confirm Update, or Update all for a sequence that stops on failure. Studio never closes other applications or forces a reboot.

    Before continuing: To update Studio itself, close it and run its verified MSI. Downloads can be cancelled before MSI; during MSI use Windows Installer Cancel.

  6. Check the version actually installed

    Wait for the installer to finish and review Studio details again. Open the installed application and confirm its version; retain failure logs. A downloaded file is not a completed installation.

    Before continuing: The Cancel button was observed, but the last test did not establish button-driven rollback. Distribution checks do not replace production acceptance or validate a DOSY measurement.

WHEN COMPLETE

Check the version that actually opens.

Retain the confirmed version, location and installation status, with logs if a failure occurred. Projects and results are reviewed in Prime or ResinAtOnce; Studio neither migrates nor recalculates them. Successful installation does not validate a scientific result.
