Remove VLC silently

I'm quite new to Powershell, so I might have missed something obvious, but i'm trying to uninstall a specific VLC version (2.2.8) silently via PowerShell, it seems to run the script, but the VLC version still remains installed.

UninstallString: C:\Program Files\VideoLAN\VLC\uninstall.exe

The script works with MSI uninstall, but not from the uninstall string from the exe I've tried to remove some of the parameters like /quiet and /qn to see the CMD window but it just blinks and then closes in 1 second.

Any help will be appreciated!

$x64App  = Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall' |  Get- 
ItemProperty |
    Where-Object {$_.DisplayName -match "vlc" -and $_.DisplayVersion -match "2.2.8" } |
        Select-Object -Property DisplayName, UninstallString, Displayversion

$x86App = Get-ChildItem 'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*' |  
Get-ItemProperty |
    Where-Object {$_.DisplayName -match "vlc" -and $_.DisplayVersion -match "2.2.8" } |
        Select-Object -Property DisplayName, UninstallString, Displayversion

if ($x64App)
{
$UninstallPath = ($x86App |Get-ItemProperty UninstallString)
Start-Process cmd -ArgumentList "/c $UninstallPath /norestart" -wait
}

elseif($x86App)
{
$UninstallPath = ($x64App |Get-ItemProperty UninstallString)
Start-Process cmd -ArgumentList "/c $UninstallPath /norestart" -wait 
}
