Using PowerShell to deploy the Coro Agent to Windows devices

Use the following PowerShell script to deploy the Coro Agent on Windows endpoint devices. Run the script on individual devices for standalone deployment or use a remote monitoring and management (RMM) platform to deploy it to multiple devices:

Important

When deploying the Coro Agent via an RMM, run the script under the Local System account (SYSTEM) to ensure it has the necessary permissions.

########################

# IMPORTANT #

# This script requires elevated privileges (Run PowerShell as Admin) to run.
# If you are deploying it via GPO or any other RMM, they will already run it in elevated mode, unless specifically configured otherwise.
# However, if you run it locally as a user, you must make sure your PowerShell instance is elevated (Run PowerShell as Admin), otherwise the script will fail.

# This script can be used both locally and with GPO or any other RMM that support PowerShell. However, some specific RMMs only support limited PowerShell commands, so this script might not work on these. In this case, please contact Coro support for help. 

########################

#Add the Coro installation URL below (in between quotes ""). You can obtain the URL from your Coro Workspace (go to Control Panel -> Devices. Scroll down
#to the latest Windows version, select the Actions button, then select Copy URL. From the Copy Invite Link dialog, select Copy.) Finally, paste the URL below.

$url = "Add the Coro installation URL obtained from Coro Workspace here. Do not delete the quotes"

#The URL above contains a string named CoroInstaller_XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.msi (where X represents random numbers). Paste this string below (in between quotes "").

$newFilename = "Add the Coro msi package from the URL here. For example, CoroInstaller_1b16c978-cd39-49bf-8809-7b4e87227e4e.msi. Do not delete the quotes"

###########################
# FOR SPECIFIC CASES ONLY #

#Set the variable below to $false if you want the script to bypass Coro installation check.
#This might be useful in some specific cases when it is required to reinstall Coro over the corrupted version.
#However, please note that this method not work in all cases. In such cases Coro needs to be uninstalled first and then reinstalled.

$checkCoroInstall = $true #Use only when asked to do so by Support: set this variable to $false to instruct the script bypass Coro installation check.

Replace the following variable markers in the script with real values:

$url : The download URL for the latest version of the Coro Agent installer for Windows, obtained from the Coro console. For details, see Deploying Coro on Windows devices .
$newFilename : The .msi installer filename, extracted from the download URL.

Standard deployment script variables

For example, if you use the following download URL: https://s3.amazonaws.com/client-repo.coro.net/beta/win/releases/2.0.412.1/CoroInstaller.msi?response-content-disposition=attachment%3B%20filename%3DCoroInstaller_123abc-456def-789abc.msi&AWSAccessKeyId=AKIA5XP6&Signature=y4V3Tq2dU9mE%3D&Expires=2005954595

This results in the following script values:

Make sure you do not delete the quotation marks when replacing the placeholder text.

note

Coro generates a unique installer filename for each workspace. Therefore, you must create a copy of the standard Coro deployment script and repeat this process for each workspace.
