When Salesforce for Outlook (SFO) is installed on a Windows computer, each version of SFO creates a unique entry in the Windows Registry called a GUID (Globally Unique Identifier). A GUID is a 32-character alphanumeric string, enclosed in curly braces, that uniquely identifies an installed application in the Windows operating system.
The GUID for each SFO version is stored in the following registry path:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
Note — Salesforce for Outlook is retired. Please review the Salesforce for Outlook Retirement article for details.
This article provides a reference table of GUIDs for each SFO version and explains how to find the installed GUID using the Windows Command Prompt.
The Windows Management Instrumentation Command-line (WMIC) tool allows you to query installed applications and retrieve GUID information. This is useful when diagnosing SFO installation issues or providing details to Salesforce R&D.
To find the GUID of the installed SFO version:
WMIC and press Enter.wmic:root\cli> prompt, run the following command to generate an HTML report of all Salesforce for Outlook installations:/output:C:\sfo\Software.html product where "name like '%Salesforce for out%'" get /format:htable
Note: Create the output file path (e.g., C:\sfo\Software.html) manually before running the command. The command may take a few seconds to complete. Run as Administrator to avoid "alias not found" errors.
To get a list of all installed applications in a text file, run:wmic /output:software.txt product get /format:htable
To get a detailed list including name, version, install date, and GUID (listed as IdentifyingNumber), run:/output:c:\software.html product get Name, Version, IdentifyingNumber, InstallDate, InstallLocation, InstallSource, Vendor /format:htable
