No solution was presented for finding where the Add-ins are installed, unless using a policy (we are not). &nbsp;We found a workaround for this particular situation, using Procmon to find the dll files that are installed, and recreating it in a script.<br />
<br />
Overall, it is not a pretty solution, but it worked for this instance

Is there a VBScript that I can execute on remote workstations to centrally log what Internet Explorer add-ons are installed on that machine? &nbsp;I am hoping to run this against all the PCs in our company to ensure that a specific add-in is loaded.<br />
<br />
Thanks.

VBScript to list I.E. Add-ons

VBScript (Visual Basic Scripting Edition) is an interpreted scripting language developed by Microsoft that is modeled on Visual Basic, but with some important differences. VBScript is commonly used for automating administrative and other tasks in Windows operating systems (by means of the Windows Script Host) and for server-side scripting in ASP web applications. It is also used for client-side scripting in Internet Explorer, specifically in intranet web applications.
