Atera removed from console, need it to come back

If you delete an agent from the console, it can still be running on the client, but not show up in our dashboard. You need to delete a few registry keys then reinstall the agent of that client. This powershell script is also hosted on itstuff.ultrex.com for ease of copy/paste from target device.

Run the following fully in command line (ignore any errors). Then reboot machine, then reinstall Atera Agent.

# Stop Atera service if running

Write-Output “Stopping Atera services…”

Stop-Service -Name “AteraAgent” -Force -ErrorAction SilentlyContinue

Stop-Service -Name “AteraAgentHelper” -Force -ErrorAction SilentlyContinue

# Kill lingering processes

Write-Output “Killing Atera processes…”

Get-Process -Name “AteraAgent*” -ErrorAction SilentlyContinue | Stop-Process -Force

# Uninstall via MSI if registered

Write-Output “Checking for MSI uninstall entry…”

$msi = Get-WmiObject -Class Win32_Product | Where-Object { $_.Name -like “Atera*” }

if ($msi) {

    $msi.Uninstall()

}

# Remove leftover folders

Write-Output “Removing leftover directories…”

$paths = @(

    “C:\Program Files\Atera Networks\AteraAgent”,

    “C:\Program Files (x86)\Atera Networks\AteraAgent”,

    “C:\ProgramData\Atera Networks\AteraAgent”

)

foreach ($path in $paths) {

    if (Test-Path $path) {

        Remove-Item -Path $path -Recurse -Force -ErrorAction SilentlyContinue

    }

}
