Check this snippet, it is using WMI but in another way, and has almost never failed me :

function Uninstall-Application($computer, $target) {
    $productInfo = Get-WmiObject Win32_Product -Filter "Name LIKE '%$target%'" -ComputerName $computer
    $pin = $productInfo.IdentifyingNumber
    $pn = $productInfo.Name
    $pv = $productInfo.Version

    if($pn -ne $null) {
        $classKey = "IdentifyingNumber=`"$pin`",Name=`"$pn`",version=`"$pv`""

        $uninstallReturn = ([wmi]"\\$computer\root\cimv2:Win32_Product.$classKey").uninstall()
        if($uninstallReturn.ReturnValue -ge 0) { Write-Host "Uninstall complete" }
        else { $uninstallReturn | Out-Host }
    } else {
        Throw "Product not found"
    }
}

Example usage :

Uninstall-Application "127.0.0.1" "firefox"
