CaniVIZ Free vs Pro: What You Get Without Paying

Troubleshooting CaniVIZ Free: Tips and Fixes

1. Confirm system requirements

• OS: Windows ⁄₁₁ (64-bit) or macOS 11+ — ensure your OS is up to date.
• RAM: Minimum 8 GB (16 GB recommended for large datasets).
• GPU: Integrated GPUs may work but a dedicated GPU (NVIDIA or AMD) improves performance.
• Storage: At least 2 GB free for app + additional space for images.

2. Install and update issues

• Run installer as administrator (Windows): Right-click → “Run as administrator.”
• Allow permissions (macOS): If macOS blocks install, open System Preferences → Security & Privacy → Allow.
• Corrupt download: Re-download from the official source and verify file size/checksum if provided.
• Update the app: Check the app’s About or Help menu for updates; reinstall the latest version if needed.

3. App won’t start or crashes on launch

• Restart device to clear temporary conflicts.
• Check logs: Look for an application log file (often in AppData on Windows or ~/Library/Logs on macOS) and note errors.
• Disable antivirus/firewall temporarily to rule out blocking.
• Start in safe mode (if available) to isolate plugin or extension issues.
• Reinstall: Uninstall fully, remove leftover folders (AppData/Library), then reinstall.

4. Slow performance or lagging

• Close other heavy apps (browsers, video editors, VMs).
• Reduce image resolution or number of concurrent datasets loaded.
• Enable GPU acceleration in app settings if available.
• Increase virtual memory/pagefile on Windows if RAM is low.
• Update GPU drivers from NVIDIA/AMD/Intel official sites.

5. File import/export problems

• Supported formats: Confirm the image/scan format is supported (DICOM, PNG, TIFF, etc.).
• File corruption: Try opening the file in another viewer; re-export from the original system if possible.
• Large files timeout: Move large files locally (avoid network drives) before importing.
• Permissions: Ensure the app has read/write access to the folder containing files.

6. Display or rendering artifacts

• Update graphics drivers.
• Toggle rendering modes in settings (e.g., switch between CPU/GPU rendering).
• Check color/Profile settings—some displays or export profiles cause color shifts.
• Test with another monitor or change display scaling to 100%.

7. Crashes while processing or analyzing images

• Process smaller batches to isolate problematic images.
• Check for unsupported metadata or corrupted tags — strip metadata and retry.
• Consult app logs for stack traces and error codes to search support resources.

8. Networking, licensing, or activation issues

• Check internet connection and proxy settings.
• Whitelist the app in corporate firewalls or proxy rules.
• Verify license key format and copy/paste without extra spaces.
• Contact vendor support with license ID and logs if activation fails.

9. Common error messages and quick fixes

• “File format not recognized”: Convert file to a supported format (e.g., DICOM).
• “Out of memory” / OOM: Close other apps, reduce dataset size, or upgrade RAM.
• “Cannot connect to server”: Check DNS/proxy and try a different network.

10. When to collect info for support

Provide the following when contacting support:

• App version and OS version.
• Steps to reproduce the problem.
• Log files (attach if allowed).
• Sample problematic file or a short screen recording showing the issue.
• Error messages or codes.

11. Preventive maintenance

• Keep the app and OS updated.
• Regularly archive and clean old datasets.
• Maintain up-to-date GPU drivers.
• Use stable storage (avoid editing files directly over flaky network shares).
