7. Common Issues & Troubleshooting

| Symptom | Likely Cause | Remedy | |---------|--------------|--------| | “Invalid license key” | – Typo, wrong format, or key meant for a different product version. | Re‑enter the key; verify that the key is for VT‑15, not an earlier version. | | “License already in use on another device” | Key is bound to a different hardware fingerprint (e.g., used on a second PC). | De‑activate the key on the original machine via Help → Deactivate License, then re‑activate here. | | “Cannot connect to activation server” | Firewall, proxy, or DNS blocking activation.visualtypewriter.com. | Add an outbound rule for port 443 to the firewall; configure proxy settings in Settings → Network. | | Activation fails after Windows update | Registry or driver changes altered the hardware ID. | Run the Re‑activate wizard (Help → Reactivate License). If still failing, contact support with the activation log (%APPDATA%\VisualTypewriter\logs\activation.log). | | License expires unexpectedly | Time‑limited (trial or subscription) key; subscription not renewed. | Purchase/renew a subscription; apply the new key. | | Application runs in “Trial” mode despite key entry | The key was entered but not validated (offline mode without response file). | Repeat online activation or correctly complete offline steps. | | Error “DLL not found – VTCore.dll” | Incomplete installation or missing system components. | Re‑run the installer Run as administrator; ensure the Visual C++ Redistributable 2019 is installed. | The Complete Guide to Visual Typewriter 15: License

8. Security & Compliance

| Area | Recommendation | |------|----------------| | License storage | VT‑15 stores the activation token in the encrypted registry key HKLM\Software\Microsoft\Cryptography\MachineGuid + HKLM\Software\Visual Typewriter\VT15\Token. Ensure the system drive is encrypted (BitLocker or equivalent). | | Backups | Do not back up the activation token as a plain‑text file. If you need to migrate to new hardware, use the Transfer License feature within the application. | | Software updates | Enable automatic updates (default) to receive security patches that also refresh the activation handshake. | | Compliance | Retain the purchase receipt and license key in a secure location for audit purposes. For enterprise deployments, maintain a central inventory of all VT‑15 keys. | Requirements

• UI: License Activation screen reachable from first-run and Settings > License.
• Input: Text field for license key (case-insensitive), Paste button, QR-scan option, drag-and-drop of .lic file.
• Validation: Local format check (regex), immediate inline errors, copy/paste sanitization (trim, remove invisible chars).
• Network: Secure HTTPS activation API with retry/backoff and exponential timeout.
• Offline: Manual activation workflow using generated Hardware ID and downloadable activation request file; ability to import activation response (.rsp) to complete activation.
• Security: Keys stored encrypted in OS-protected secure storage (Keychain/Windows DPAPI/Linux libsecret), no plaintext logs, rate-limit attempts, and obfuscate keys in UI.
• UX: Progress states, success confirmation including license type and expiry, and clear error messages with next steps.
• Logging: Local encrypted logs for troubleshooting; option to upload anonymized logs to support when user consents.
