The uninstall string contains the path to the uninstall executable together with parameters, you try to run that together with a /s argumentlist...
My example script was for checking the existence of the software and then running the correct invoke-command with the uninstall executable and parameters in the argumentlist.

if (test-path -path "C:\Program Files (x86)\InstallShield Installation Information\{286A9ADE-A581-43E8-AA85-6F5D58C7DC88}\DellOptimizer.exe" ) {invoke-command -scriptblock {'C:\Program Files (x86)\InstallShield Installation Information\{286A9ADE-A581-43E8-AA85-6F5D58C7DC88}\DellOptimizer.exe'} -ArgumentList "-remove -runfromtemp"}

}

Strange, the -argumentlist is a valid parameter for invoke-command?

    invoke-command -scriptblock {'C:\Program Files (x86)\InstallShield Installation Information\{286A9ADE-A581-43E8-AA85-6F5D58C7DC88}\DellOptimizer.exe'} -ArgumentList '-remove -runfromtemp'
    }
    You can always put this in the script that you use for other packages, if it's not there then you will receive an error but it should uninstall it when present
