Issue/Introduction

When migrating from the executable (.exe) installer to the Windows Installer package (.msi) for the Outlook EncryptionAdvanced add-in, system administrators may notice discrepancies in both configuration settings and visual branding post-installation.

Specifically:

• Branding Mismatch: Opening About within the Outlook add-in displays Echoworx instead of Symantec.

• Registry Misconfiguration: The MSI deployment fails to apply default registry settings, causing add-in options to function incorrectly or revert to unconfigured defaults.

Resolution

To ensure options are configured correctly and the appropriate Symantec branding is applied, you must execute the MSI installer alongside its corresponding transform file (.mst).

Follow these steps to complete the installation:

1. Locate your deployment directory containing both the .msi package and the .mst transform files.

2. Identify the correct Symantec transform file. While filenames vary depending on your specific release package, look for a file pattern matching GatewayEncryption_Symantec.mst.

3. Open an Elevated Command Prompt (Run as Administrator) or update your software deployment tool (e.g., Microsoft Intune, SCCM).

4. Run the installation using msiexec.exe with the TRANSFORMS property specified:

msiexec.exe /i "C:\path\to\MSI\file\GatewayEncryption.msi" TRANSFORMS="C:\path\to\MSI\file\GatewayEncryption_Symantec.mst"

Note: Replace C:\path\to\MSI\file\ with your actual local or network directory path. If deploying silently across an enterprise network, append /qn to the command.

Verification

1. Relaunch Microsoft Outlook.

2. Open the add-in options and select About.

3. Confirm that the branding displays Symantec and that your custom registry settings are actively reflected in the add-in configuration.
