Powershell Script

Help & Support
1

Is it possible to write a Powershell script that would download the communication agent from the link and install it? So that I can then deploy the agent using the procedure in the console? Could someone help in the preparation of such a script?

You can use this Update Comodo Client Communication to latest version (itarian.com)

You can import this procedure and run it. Any specific reason you want powershell script and not the default python? This script helps you meet your objective.
Powershell script is not directly supported as of yet but maybe in the future. So if you really want PowerShell element in the procedure script then the following can be used as well. It will download the file in C:\Temp folder and then install it. It wont reboot it, so you can plan your reboot at desired time. The powershell file that downloads the file will be created on the target workstation where %TEMP% variable is pointing to and once it has done its job, it will delete that file. You can make changes to the script based on which folder you want to use for downloading the file.
