Update & uninstall

Check for updates

Open Excel → tab DVD Addin → group About → click split-button About (DVD icon) → menu Check Update.

The addin calls dvdpm.net's check-update server:

• If a new version exists → dialog with:
  • New version number (e.g. 2.7.8).
  • Release notes.
  • Download button → opens browser to the download link.
  • Skip button → close dialog.
• If you're already on the latest → message "You're on the latest version".

Download the new setup.exe → close Excel → run → installer auto-uninstalls old version and installs over (Major Upgrade).

Auto-check (background)

DVDAddin auto-checks for updates each time Excel starts + addin loads. If a new version exists:

• Small notification at the bottom corner (doesn't block workflow).
• Click the notification to open the update dialog above.

Disable auto-check in Preferences → General → Auto-check update.

Uninstall

Method 1 — Via Windows Settings (recommended)

1. Open Settings → Apps → Installed apps (Windows 10/11).
2. Find DVDAddin.
3. Click 3-dot → Uninstall → confirm.

Method 2 — Via Control Panel (legacy)

1. Open Control Panel → Programs → Programs and Features.
2. Find DVDAddin in the list.
3. Right-click → Uninstall.

Method 3 — Run an existing setup.exe

1. Re-download setup.exe of the same version.
2. Run setup.exe → wizard shows 3 options:
   • Modify — change components (not used for DVDAddin).
   • Repair — re-install files (fix when addin malfunctions but you don't want to uninstall).
   • Remove — fully uninstall → pick this.

What remains after uninstall

Uninstall does NOT delete:

• Settings in registry: HKCU\Software\DVD\DVDAddin\* (API keys, Preferences, Translate language, Gantt config, License token).
• Local license: %LocalAppData%\DVDAddin\license.dat.
• Offline grace cache: registry value LastLicensedAtUtc.

Reason: if you reinstall later, settings + license are auto-recognized — you don't need to re-enter API keys, re-login license, etc.

Want a complete clean (clean slate)

Open Registry Editor (regedit), delete the key:

HKEY_CURRENT_USER\Software\DVD\DVDAddin

Delete the folder:

%LocalAppData%\DVDAddin

Careful

After this delete, you must re-login your license + re-enter all API keys (Gemini, OpenAI, Groq, Cerebras). Only do this when truly resetting (e.g. before selling the machine).

Re-install

If the addin has an unidentified error:

1. Uninstall (Settings → Apps → Uninstall).
2. Restart your machine (ensures .xll file isn't held).
3. Install from the latest setup.exe.

Settings + license are preserved (no re-login needed).
