I cannot uninstall the zabbix agent from my server

[marcelin]

Good morning gentlemen.
I deleted the agent zabbix files from my server 2012 so that I could download again, but I can't install another agent zabbix because the old agent zabbix service (stop) is on the machine and there is no other agent zabbix file

Hi marcelin,
Your zabbix service still exists. What agent version for which OS you are trying to remove?
Kind regards

Hello, Marceli, first make sure that you have the ability to execute PowerShell scripts. Issue the following command in PowerShell admin: "Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUse"

Below is a PowerShell code that searches for clients with both Zabbix Agent 1 and 2, regardless of whether they are 32 or 64-bit versions, using the keyword "zabbix".
It removes all related directories and files. In the second part, it checks the registry to make sure that the Zabbix keys have been deleted and then removes the service.

#remove all zabbix cleint and local dir

Write-Host "Detecting current Zabbix Agents"
Start-Sleep -Seconds 2

$searchString = "Zabbix"

$packages = Get-Package -Name "*$searchString*"
Clear-Host

if ($packages.Count -eq 0) {
    Write-Host "No packages containin $searchString found"
    Start-Sleep -Seconds 2
} else {
    Write-Host "The following packages were found::"
    Start-Sleep -Seconds 2
    $packages | Format-Table -AutoSize

    foreach ($package in $packages) {
        Uninstall-Package -Name $package.Name -Confirm:$false
        Write-Host "Pakiet $($package.Name) został odinstalowany."
        Start-Sleep -Seconds 2
        Clear-Host

        # Delete related directories
        $installPath = $package.InstallLocation
        if ($installPath) {
            Remove-Item -Path $installPath -Recurse -Force
            Write-Host "Directory $installPath has been deleted."
            Start-Sleep -Seconds 2
            Clear-Host
        } else {
            Write-Host "Installation directory for package $($package.Name). not found."
            Start-Sleep -Seconds 2
            Clear-Host
        }
    }
