Powershell Uninstall using WMIC

I have a requitrment to uninstall a suite of applications using WMIC. Initially I wanted to use the below script

$ObjApp = Get-WmiObject win32_product -filter "IdentifyingNumber = '$FindAppbyGUID'" -namespace root/cimv2

 If ($ObjApp.Uninstall().ReturnValue -eq 0)
 {
    Write-Host  "Uninstall SUCCESSFULL"
 }
 Else
 {
    Write-Host "Uninstall FAILED"
 }

For whatever reason this application will not uninstall with the above code neither via msiexec /X /qn etc etc.
However the application will uninstall with below WMIC command ...

wmic product where identifyingnumber="{AAAA00A0-BB11-22CC-D333-4E4444E44444}" call uninstall

My method of running this in powershell is ...

$Cmd = "wmic product where identifyingnumber="{AAAA00A0-BB11-22CC-D333-4E4444E44444}" call uninstall"
Invoke-Expression $Cmd

I also tried ...
$Cmd = 'wmic product where identifyingnumber="{AAAA00A0-BB11-22CC-D333-4E4444E44444}" call uninstall'
Invoke-Expression $Cmd

Any Help will be appreciated.

Thank You in Advance

There are some issues with the ticks/quotes when running inside of PowerShell. And the Invoke-Command is not required. This should work:
wmic product where identifyingnumber="'{AAAA00A0-BB11-22CC-D333-4E4444E44444}'" call uninstall
