Illustrated walkthrough
Step 1. On the ribbon, open the DVD Addin tab → About group → open Help → choose Download Tool.

Step 2. No add-in window opens: your default browser opens the download link for the latest DVDAddin.rar package on the GitHub releases page. If Windows cannot open a browser, the add-in reports “Could not open browser:” with the reason.
Step 3. When the download finishes, extract DVDAddin.rar (WinRAR, 7-Zip), close every Excel window, then run the installer from the extracted folder; reopen Excel to use the new version.
Example
The estimating team takes on a new engineer whose PC has no add-in yet. From his own machine the supervisor clicks Download Tool, saves DVDAddin.rar, copies it to a USB stick and installs it on the new PC. After installation the add-in sits in C:\DVDAddin\; the new engineer just signs in with the license and the DVD Addin tab is ready to use.
Notes
- The command only opens the download link; it does not install or update anything for you.
- If Windows cannot launch a browser, the add-in shows a "Could not open browser:" warning with the error text — open the
dangdvd/DVDAddinreleases page manually in that case. - An Internet connection is required; some site networks block GitHub, so use a mobile connection or ask IT to allow it.
- The download is a
.rararchive and needs an extraction tool; your browser or antivirus may ask for confirmation before saving it. - Close all Excel windows before installing, otherwise the loaded XLL is locked and the installer errors out.
