Create one line agent install script

[asheroto]

I have a handful of computers in different locations that need agents installed. I am using ScreenConnect already. At first I was going to each machine, transferring the agent EXE, then running it, but found this tedious for many computers. I wrote a quick PowerShell script that will take the agent EXE's URL and generate a PowerShell script to download and install it. It converts the script into an encoded command (base64) so that it can be easily copy-and-pasted. It also adds a temporary AV exception so that the agent installer isn't flagged (I found this to be a problem without doing so).

A great feature would be adding something like this to TacticalRMM natively so you could just copy-and-paste a single line command to install the agent for the location.

Gist of my PowerShell script is here:

There is a simple native script to install TRMM using the screenconnect command interface as well:

Gotcha. The main reason I didn't use that is because it doesn't exclude AV for Windows Defender when downloading/installing the agent. The agent installer adds Windows Defender exclusions, but not for the agent installer itself.

I'm code signed, so never have a problem...unsigned you might need some exclusions in there as well:

powershell Add-MpPreference -ExclusionPath C:\TEMP\TRMM
    powershell Add-MpPreference -ExclusionPath "C:\Program Files\TacticalAgent\*"
    powershell Add-MpPreference -ExclusionPath C:\Windows\Temp\winagent-v*.exe
    powershell Add-MpPreference -ExclusionPath "C:\Program Files\Mesh Agent\*"
    powershell Add-MpPreference -ExclusionPath C:\Windows\Temp\TRMM\*

Gotcha.

Those exclusions are fortunately added after the agent is installed by the agent installer.
