Extract the ZIP File
Right-click the downloaded M365_Copilot_ROI_Calculator_Local.zip and select "Extract All..." or use your preferred extraction tool. Choose a location you can easily find (like your Desktop or Documents folder).
Open the Extracted Folder
Navigate to the folder where you extracted the files. You should see all the HTML files, a lib folder, and the launcher scripts.
Run the Launcher
Double-click the launcher file for your operating system:
Double-click RUN_LOCAL_SERVER.bat
Double-click RUN_LOCAL_SERVER.sh
💡 The launcher will start a local web server and automatically open the calculator in your browser at http://localhost:8000
Alternative: Open index.html Directly
You can also simply double-click index.html to open it directly in your browser, though the launcher method is recommended for the best experience (it avoids potential file:// protocol restrictions).
