Troubleshooting blocked downloads

When you download the Neurocad desktop service installer, your browser or operating system may flag or pause the download. The Neurocad installer is digitally signed. These warnings appear because the file is new and not yet widely downloaded, which security tools treat as low reputation. This is expected for early access software, and the steps below will let you complete the download and installation.

Browser warnings

Google Chrome

You may see a message that the file is not commonly downloaded.

1. Press Ctrl + J (Cmd + Shift + J on Mac) to open Downloads
2. Find the paused file
3. Click the three dots next to the file and select Keep
4. Confirm by clicking Keep anyway

Microsoft Edge

You may see a message that the file isn't commonly downloaded, triggered by the SmartScreen filter.

1. Hover over the warning in the downloads bar
2. Click the three dots icon
3. Select Keep, then click Show more, then select Keep anyway

Mozilla Firefox

You may see a warning when the download completes.

1. Click the Downloads arrow icon in the toolbar
2. Right-click the flagged file
3. Select Allow Download

Operating system warnings

After the download completes, your operating system runs its own check when you open the installer.

Windows 11 and 10

Microsoft Defender SmartScreen blocks files without an established reputation. You may see a blue banner reading "Windows protected your PC."

1. Click More info, directly under the warning text
2. Click Run anyway

macOS

Neurocad Link is available for macOS (and Intel-based Macs). If you run into installation issues on an Intel-based Mac, email support@neurocad.com.

Gatekeeper blocks software it cannot verify. You may see a message that Apple could not verify the app is free of malware.

1. Click Done or Cancel on the popup
2. Open System Settings and go to Privacy & Security
3. Scroll to the Security section
4. Find the message stating the app was blocked and click Open Anyway
5. Enter your Mac password or use Touch ID to authorize

Installation requires administrator permission

Administrator blocks are different from security warnings. They mean your user account doesn't have permission to install software, which is common on company-managed machines.

You're facing an administrator restriction if a User Account Control prompt asks for an admin username and password, the Yes button is greyed out or missing, you see an Access Denied error, or the installer closes abruptly without completing.

On Windows, right-click the installer and select Run as administrator. If you don't have admin credentials, you'll need your IT team to enter them or approve the install.

If your company requires IT approval for software installs, reach out to us if you need documentation to support the request.
