Install msi using Start-Process with /q switch? - powershell

Question

I want to install an msi with a /q switch, I look online and the examples don't have the /q switch and I keep getting errors.
I need something like:
$WorkingDirectory = (Split-Path $myinvocation.mycommand.path -Parent)
Start-Process -FilePath msiexec /i "$WorkingDirectory\LAPS.x64.msi" -ArgumentList /q

Answer 1

Don't bother with Start-Process. Use the call operator:
& msiexec.exe /i "$WorkingDirectory\LAPS.x64.msi" /q

Answer 2

put the whole command in the brackets
Example(Python msi):
Start-Process msiexec.exe -Wait -ArgumentList "/I $($LocalPython.FullName) /passive ALLUSERS=1 ADDLOCAL=Extensions"
replace /passive with /q

Answer 3

Not all installers are the same. To find the installer switches for your .msi use:
.\LAPS.x64.msi /?
.\LAPS.x64.msi -?
I would also store the msi path in a variable, and use an ArrayList for the arguments, something like this has worked for me in my scripts:
# Path to .msi
$msiPath= 'C:\LAPS.x64.msi'
# Define arguments
[System.Collections.ArrayList]$arguments =
#("/i `"$msiPath`"",
"/quiet")
# Start installation
Start-Process -FilePath msiexec.exe -ArgumentList "$arguments" -Wait -NoNewWindow

$path="C:\Dat\install.msi"
$parameters="/q"
$packageinstall=(split-path $path -leaf) + ' ' + $parameters
write-host $packageinstall
$computers = get-content c:\com.txt
$computers | where{test-connection $_ -quiet -count 1} | ForEach-Object {
copy-item $path "\\$_\c$\windows\temp" -Force -Recurse
$newProc=([WMICLASS]"\\$_\root\cimv2:win32_Process").Create("C:\windows\temp\$packageinstall")
If ($newProc.ReturnValue -eq 0) {
Write-Host $_ $newProc.ProcessId
} else {
write-host $_ Process create failed with $newProc.ReturnValue
}
}
