During Installation process of a software using Start-Process "msiexec.exe" ... -wait, how to fix error and continue the installation process? - powershell

Question

For the installation of the "Self-Hosted Integration runtime software, using PowerShell command
Start-Process "msiexec.exe" "/i $path /quiet /passive" -Wait, error comes up for "DIAHostService" not having "LocalSystem" access.
I have the code to change the login to the LocalSystem ("sc.exe config "ServiceName" obj="LocalSystem") But How can I do this during the Installation Process, how do I catch the error and do the required change and continue for the installation automatically?
Code:-
param([string]$path, [string]$authKey)
function Install-Gateway([string] $gwPath)
{
# uninstall any existing gateway
UnInstall-Gateway
Write-Host "Start Gateway installation"
Start-Process "msiexec.exe" "/i $path /quiet /passive" -Wait
Start-Sleep -Seconds 30
Write-Host "Succeed to install gateway"
}

Since I am in no position to replicate what you are doing, take this generic approach as an example.
param([string]$path, [string]$authKey)
function Install-Gateway([string] $gwPath)
{
Write-Warning -Message 'Starting Gateway uninstallation'
UnInstall-Gateway
Try
{
'Starting Gateway installation'
Start-Process -FilePath 'msiexec.exe' -ArgumentList "/i $path /quiet /passive" -Wait -ErrorAction Stop
Start-Sleep -Seconds 30
Write-Verbose -Message 'Gateway installation successful.' -Verbose
}
Catch
{
Write-Warning -Message 'AN error occurred'
$PSItem.Exception.Message
}
}
If you need to run this with a different user, then you need to add the RunAs as part of the Start-Process error logic. Yet using RunAs means starting a new Powershell instance. It will not run in the same process.
