1. Download the HP ALM Excel Add-in installer (Add-ins Page -> More HP ALM Add-ins -> Microsoft Excel Add-in).

2. Extract the contents of the installer (e.g., `HP-ALM-MSExcelAddin.exe`) using a program such as WinZip, WinRAR, or 7-zip.

3. The contents of the extraction consist of a folder named `Disk1` with the installer files under it (including `setup.exe`, etc.).

4. Place the `Disk1` folder in the root of your C: drive (so the absolute path is `C:Disk1`).

5. Bring up an elevated command prompt (Windows Accessories -> Right-click Command Prompt -> Run as Administrator) and execute the following command (this will generate the response file used for a silent installation):

`''C:Disk1Setup.exe'' /r /f1''c:mpsetup.iss''`

6. Perform the installation manually using the GUI of the setup. All of the configuration options chosen during the manual installation, if any, are saved in the file `mpsetup.iss` in the root of your C: drive.

7. Copy the Excel Add-in installation files (`Disk1`), along with the created `mpsetup.iss` configuration file, to your client machine(s). Deploy with the following command:

`''C:Disk1Setup.exe'' /s /f1''c:mpsetup.iss''`
