1. Download the installer ​

Download DVDAddin.rar (about 74 MB) from the official release page:

→ https://github.com/dangdvd/DVDAddin/releases/tag/DVDAddin

If DVD Addin is already installed it is quicker: DVD Addin tab → About group → Help menu → Download Tool. Extract the .rar with WinRAR or 7-Zip to get the installer DVDAddin-Setup-<version>.exe.

Requirements: Windows 10 (version 1809) or later, or Windows 11; Excel 2016 or later or Microsoft 365, 32- or 64-bit; administrator rights; about 112 MB of disk space.

2. Close Excel before installing ​

⚠️ Important

Save your work and close every Excel window before running the installer. When you install a new version while Excel is open, the installer shows a Preparing to Install page offering to close Excel for you (Automatically close the applications) — saving and closing it yourself is still safer.

Reason: the installer has to replace the .xll file Excel has loaded, and Excel keeps the old add-in in memory until it fully exits.

3. Run the installer ​

Double-click DVDAddin-Setup-<version>.exe. The setup wizard (in English) goes through:

  1. Windows protected your PC — may appear because the installer is not code-signed: click More info, check the file name, then Run anyway.
  2. Select Setup Install Mode → choose Install for all users (recommended).
  3. Windows asks for administrator rights (UAC) → Yes.
  4. Select Destination Location — only on the first install: keep C:\DVDAddin → Next.
  5. Ready to Install → Install, wait for the files → Finish.

Afterwards the Start menu has a DVDAddin Excel folder: the User Guide (PDF) / Hướng dẫn sử dụng (PDF) books (readable offline), the Practice workbooks folder and the uninstall shortcut. If Excel is not found the installer asks whether to continue anyway — you still need Excel to use the add-in.

If your machine doesn't have .NET 8 ​

The installer detects whether your Excel is 32-bit or 64-bit, then downloads the matching .NET 8 Desktop Runtime from Microsoft:

  • Excel 64-bit → downloads windowsdesktop-runtime-8.0.11-win-x64.exe (~55 MB)
  • Excel 32-bit → downloads windowsdesktop-runtime-8.0.11-win-x86.exe (~50 MB)

After downloading, .NET 8 installs silently — no intervention needed. This step needs Internet; if the download fails the installer says so and gives the manual download address https://dotnet.microsoft.com/download/dotnet/8.0 (pick the Desktop Runtime matching Excel's bitness).

If your machine already has .NET 8 ​

The installer finds .NET 8 → skips the download and installs DVD Addin straight away.

4. Upgrade from an older version ​

Run the new installer as for a first install: it installs over the existing folder (it does not ask for the folder again) — you do NOT need to uninstall the old version.

Notes:

  • Close Excel completely before installing (including any leftover EXCEL.EXE processes in Task Manager). Excel keeps the old add-in in memory until it fully exits, so installing over a running Excel leaves you on the old code — and it looks as if the new build did not fix anything.
  • Your settings (API keys, Preferences, Translate language) are preserved in registry HKCU\Software\DVD\DVDAddin\*.
  • Workbooks using the addin are unaffected.

5. Open Excel and verify ​

After installation, open Excel — you'll see 2 new tabs on the Ribbon:

  • DVD Addin — general commands (text, numbers, files, print, translate, AI).
  • DVD Cons — construction-specific commands (Gantt, rebar cutting, BoQ).

If you DON'T see these 2 tabs, see Troubleshooting below.

6. Activate license ​

On first Excel open, the addin runs in 30-day free trial mode — the License button (tab DVD Addin → group About) counts down Trial: N days left and changes to Buy License when the trial ends. To keep the locked commands after the trial, activate a license (Standard: everything except the 22 PRO commands; PRO: everything):

→ Activate license guide

Troubleshooting ​

Error: "It was not possible to find a compatible framework version for .NET Desktop Runtime" ​

This means .NET 8 is not installed for the right Excel bitness. Fix:

  1. Go to Settings → Apps → Apps installed (Windows 10/11).
  2. Find "Microsoft Windows Desktop Runtime - 8.0.x".
  3. If Excel is 64-bit but only (x86) is installed → install x64 too.
  4. If Excel is 32-bit but only (x64) is installed → install x86 too.

Direct .NET 8 download from Microsoft:

"DVD Addin" / "DVD Cons" tabs missing from Ribbon ​

  1. Open Excel → File → Options → Add-ins.
  2. At the bottom, Manage: dropdown → pick Excel Add-ins → click Go.
  3. In the list, make sure DVD Addin is ticked.
  4. If visible but not ticked → tick it → OK.
  5. If NOT in the list → click Browse... → find the .xll at:
    • 64-bit Excel: C:\DVDAddin\DVDAddin-AddIn64-packed.xll
    • 32-bit Excel: C:\DVDAddin\DVDAddin-AddIn-packed.xll

Tabs appear but buttons are grayed out ​

Common cause: no workbook is open. Create a new workbook → buttons will enable.

If still grayed after opening a workbook: license expired or revoked. See Activate license.

Other installation errors ​

Run the installer again from a command prompt with logging on: DVDAddin-Setup-<version>.exe /LOG="%TEMP%\DVDAddin-setup.log", then send that file (plus the file from Export support log if the add-in runs) to [email protected].

→ Next step: Activate license
