powrshell command does not run when I run the entire script

I wrote a ps1 script to automate some package installation but the strange part is when I run the command snippet for executing the .exe file for SEP (Symantec Endpoint Protection) , it is executing fine , but when I execute the entire script , it does run the command snippet. Iam only running a simple .exe file , and even if I run it manually , it does not show any installer , rather it installs silently in the background. So in the script, Iam only running the .exe file, thats it . Should I be giving any wait time or any other inputs ?

Start-Process -Wait -FilePath "C:\Temp\Symantec-Windows\SEP 14.3.3384.1000 x64.exe" -passthru
$SymVersion = Get-WmiObject -Class Win32_Product -ComputerName $hostname | Where-Object -FilterScript {$_.Name -eq "symantec endpoint protection"} | Format-List -Property version, InstallState, name
echo $SymVersion
if($SymVersion)
{
echo 'Symantec is successfully installed' -ForegroundColor Green 
}
else
{
echo 'Symantec is not successfully installed' -ForegroundColor Red
}
Solution

  • The symantec antivirus exe files are made for silent installations. If you want to proceed with GUI mode, better unzip the file and use MSI file with arguments. With your current script,Its better to check the process is exited with code 0. The following code is not tested.

    $process = Start-Process -FilePath "C:\Temp\Symantec-Windows\SEP 14.3.3384.1000 x64.exe" -passthru -Wait
if($process.ExitCode -ne 0)
{
    throw "Installation process returned error code: $($process.ExitCode)"
} else { Write-Host "Installation Successful"}
