Datadog Agent installation on Windows

Question

I am trying to install the Datadog agent on Windows using PowerShell only, not manual however, the APIKEY is not being setup. Is there a way to update/set the APIKEY after installation?

First you may need to download the MSI file:

$image_url = "https://s3.amazonaws.com/ddagent-windows-stable/ddagent-cli-latest.msi"
$destin = "C:\path\to\downloaded\ddagent-cli-latest.msi"
(New-Object System.Net.WebClient).DownloadFile($image_url, $destin)

The actual powershell command for installation (with extra optional arguments included as arguments):

msiexec /i C:\path\to\downloaded\ddagent-cli-latest.msi /l*v C:\path\to\installation_log.txt /quiet APIKEY="$DD_API_KEY" HOSTNAME="$HOSTNAME" TAGS=`"$TAGS,COMMA,DELIMITED`

It's been a while since i've done this (8 months or so?), so it could be outdated, but it used to work :).

Note, if you're running this from a remote provisioning script, you'll probly have to schedule this to be executed not-remotely so that the installation command can be run with heightened permissions, which i believe is required. And you may need to make sure the computer is plugged into the power source (i remember hitting some infuriating issue where that was an arbitrary requirement for Windows scheduled tasks to run, and Windows didn't allow me to configure around that).
