Verification Step: After downloading, right-click the file → Properties → Digital Signatures tab. You should see "Sivantos GmbH" or "WS Audiology" as the signer. This confirms the file has not been altered.
✅ Stable & Complete Installation – The verified download contains all core modules (Connexx, Connexx Link, and the embedded database). No unexpected crashes during installation or device detection.
✅ Wide Device Compatibility – Supports Signia Pure, Motion, Styletto, and legacy Siemens devices (e.g., Aquaris, Pure Carat). The verified version includes up-to-date firmware libraries.
✅ Verified Hash/Signature – A genuine download comes with an MD5/SHA256 checksum or digital signature. This guarantees the file hasn’t been tampered with—critical for medical software.
✅ Offline Functionality – Unlike some cloud-only systems, verified Connexx 9 works fully offline after installation, which is a plus for clinics with unstable internet.
✅ No Hidden Adware – Many unverified “free” downloads bundle toolbars or miners. The verified version is clean, as confirmed by scans on VirusTotal (0/60 detections).

Overall Rating: 4.6/5

If you use Noah 4 or Noah 5:
After you have the verified Connexx_9_setup.exe, follow these steps precisely.
Step 1: Disable Antivirus Temporarily (Crucial) Windows Defender often flags the SQL Server installation as a false positive. Disable real-time protection just for the installation period, then re-enable it after.
Step 2: Run as Administrator Right-click the installer → Run as Administrator. Do not simply double-click.
Step 3: Accept the License Agreement Read the EULA carefully. The verified version will contain Signia’s official copyright notice (2021-2023). Cracked versions often have missing or altered legal text.
Step 4: Select Installation Type
Step 5: Driver Installation Prompt When Windows asks "Do you want to install this device software?" click "Install" . The verified drivers are signed with a valid certificate from "Sivantos Pte. Ltd."
Step 6: Database Configuration
The installer will launch SQL Server setup. Choose "Windows Authentication" (default) and leave the instance as SQLEXPRESS. Do not change the port (1433).
Step 7: Restart After 10-15 minutes, the system will require a restart. Do not skip this—the Noahlink driver only initializes on reboot.
