Creating a Job to run function in the background

Evening all

I have 2 questions about my script below.

The script installs symantec anti virus remotley.

  1. How do i turn this into a job so it doesn’t hang my app when it’s running the function

  2. The Win 7 part works fine but for XP it does not install… It copies the files over correctly but doesn’t seem to run the msi … I’ve checked event view and nothing there.

Any assistance would be appriciated.

function SEPInstall {

$HostName = $InputBoxHW.text;

if([System.Windows.Forms.MessageBox]::Show("This will install SEP 12 on $HostName and reboot. Continue?", "SEP 12 Install",[System.Windows.Forms.MessageBoxButtons]::OKCancel) -eq "OK")

sleep 2

$outputsepinstall.text = write "Copying required files to $HostName"
 sleep 5
 $service = Get-Service 'RemoteRegistry' -cn $HostName
 If ($service.Status -match 'Stopped') {
 If (!(Test-Path \\$HostName\c$\temp\AVInstall\)) {
 mkdir \\$HostName\c$\temp\AVInstall\
 $os_type64 = (Get-WmiObject -ComputerName $HostName -Class Win32_ComputerSystem).SystemType -match '(x64)'
if ($os_type64 -eq "True") {$files = Get-ChildItem "\\DFS-EMEA\Distribution\Ldn\InstallerPackages\IWSEP12RU564B0100\"}

 $os_type32 = (Get-WmiObject -ComputerName $HostName -Class Win32_ComputerSystem).SystemType -match '(x86)' 
if ($os_type32 -eq "True") {$files = Get-ChildItem "\\DFS-EMEA\Distribution\Ldn\InstallerPackages\IWSEP12RU532B0100\"}

 Foreach ($file in $files) {
 Copy-Item $file.fullname "\\$HostName\c$\temp\AVInstall\" -recurse
 $outputsepinstall.text = write "Installing SEP12 on $HostName"
 sleep 5
 if ($os_type64 -eq "True") {$process = Invoke-WMIMethod win32_process -name create -cn $HostName -ArgumentList 'msiexec /i "c:\temp\AVInstall\Sep64.msi" /qb'}

 if ($os_type32 -eq "True") {$process = Invoke-WMIMethod win32_process -name create -cn $HostName -ArgumentList 'msiexec /i "c:\temp\AVInstall\Sep.msi" /qb'}
 $id = $process.processid
 $a = ""
 do {
 $a = Get-Process -cn $HostName | Where{$_.ID -match "$ID"}
 While ($a -ne $null)

 del \\$HostName\c$\temp\AVInstall -force -recurse
 $outputsepinstall.text = write "Removing temp files from $HostName"
 sleep 10
 $outputsepinstall.text = write "Rebooting $HostName"
 sleep 5
 Restart-Computer -ComputerName $HostName -force

 sleep 40
 $outputsepinstall.text = write "Waiting for logon service to start"

$status = (get-service -Name NetLogon -ComputerName $HostName).Status}
Until ($status -eq "Running") 
$outputsepinstall.text = "$HostName is Online"}

Invoke-WmiMethod has a -AsJob parameter. But, does de MSI install work when you execute this line directly?

Invoke-WMIMethod win32_process -name create -cn $HostName -ArgumentList 'msiexec /i "c:\temp\AVInstall\Sep64.msi" /qb'

I just kicked it off and i can see the event view details on the install.

I’ve also figured out my the 32bit verion on XP isn’t working.
It doesn’t seem to be creating a processID.

Is there anyway i can force it to?

Are you getting any error messages in the eventlog? Or on the console? Try using -Verbose.

I’ve done some research and its returnvalue 3 (Insufficient Privilege)

No idea how to get round this

I found that

Invoke-WmiMethod -Path Win32_Product -Name Install -ComputerName "GBRPWMVDI023615" -ArgumentList @($true,$null,"\\GBRPWMVDI023615\c$\temp\AVInstall\Sep.msi")

Works for installing but how do i monitor that there isn’t a processid property on win32_product
