    Hi All,

    I need to uninstall the old driver and install the new one.
    If I install the new, it pops up saying I need to uninstall the old first
    If I try to uninstall, it pops up saying that it'll require a reboot and do I want to continue.

    I've tried numerous switches like /S, /silent, -force, etc...

    I'm looking to see if anyone has done this or knows how to do this. All my attempts fail do to a popup during the uninstall. If I run the below script it just hangs and tries to continue to run, because I assume it's waiting for a response from the popup.

    Any pointers appreciated. There a number of machines needing the update, otherwise I'd just do it manually.

    #Look for and obtain uninstall string for Synaptic
    $Synaptic = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall |
    Get-ItemProperty |
    Where-Object {$_.DisplayName -like "Synaptics Pointing Device*" } |
    Select-Object -Property DisplayName, DisplayVersion, UninstallString

    #Perform an uninstall first.
    ForEach ($Syn in $Synaptic) {

    If ($Syn.UninstallString) {

    $uninst = $Syn.UninstallString
    $uninst = $uninst.Replace('{',' ').Replace('}',' ')

    $Null = Invoke-Expression $uninst -ArgumentList '/S' -ErrorAction Stop
    Write-Error "Uninstall failed because... The error is: $($_.Exception.Message)"
    Exit 1


    #Perform the install of the new version
    Try {
    $Null = Start-Process sp81892.exe -ArgumentList '/S' -ErrorAction Stop
    Catch {
    Write-Error "Install failed because... The error is: $($_.Exception.Message)"

    Exit 1

    Exit 0

    If the driver doesn't allow a fully silent uninstall (and many don't), then there's not much you can actually do.
