Here is a small script that helps in reducing the manual effort needed to identify if the application [that has to be packaged] is installing any Microsoft Office add-ins.
During Source Validation or Packaging, if there is a requirement to identify whether the application installs any Office add-ins [Word,Excel,PowerPoint,Outlook etc...] then packager can identify the add-ins [application or COM] using this script.
You can change the script accordingly to save the CSV file to the location you wanted. I have included a notification message at the end of the execution.
Hope this helps.
