Fully Automate deployments of GoToMeeting Updates – Part 2

November 12, 2013 by Rob Plank·1 Comment

In Part 1 of this blog post we covered the main control runbooks. In this post I am going to cover the main PowerShell script that will check if there is an update available on the Citrix website and download the update if a new version is found.

we will be creating the runbook that I called “Check for Update” in runbook 2

Check for new Version and download

In the above powershell script I am downloading the current version of the GoToMeeting client and checking to see if the version number is newer than the last downloaded version, if it is newer we flip a bool variable to equal true. We return this variable and use it as a filter in the main control Runbook.

Return Data

That’s good. So now gotomeeting gets automatically updated to a newer version if any, similar to RHUB web conferencing appliances.
