Serial Number Report

Carlson Software is setup (by default) to check the Carlson server for periodic updated patches (aka "service packs"). These checks are logged so that the server collects which build versions a particular machine is running. On the www.carlsonsw.com webpage, under the Support > Product Registration, there is a link for a report of this serial number information:
http://update.carlsonsw.com/current_version_report.php

This tool generates a patch status report for all the computers at your company.

This link goes to a webpage which prompts for the account to report. A serial number must be supplied along with either a phone number or Carlson customer ID assigned to the serial number.

A report is then generated with all the machines, serial numbers and current build numbers and last update check date for the identified account as shown in the sample below (parts of the serial numbers below have been blurred for security purposes).
