Converting msiexec command from cmd to powershell

问题

In my powershell script, I need to run couple of msiexec commands quietly. The problem is when I try to run the command, the Windows Installer help popup shows rather than executing the command. (Below Image)

The same command runs well in cmd. Below is my command. I have kept the & in the command in double quotes to consider it as a string as suggested.

& msiexec /log c:\msxml.log /quiet /I "&" D:\LoadGeneratorsetup\prerequisites\msxml6\msxml6_x64.msi

I tried using Start-Process -FilePath to run this but end up with the below error.

Start-Process : A positional parameter cannot be found that accepts argument 'c:\msxml.log'.
At line:1 char:1

    + CategoryInfo          : InvalidArgument: (:) [Start-Process], ParameterBindingException

Can someone provide an details on how to execute the command quietly using powershell.

For your second command:

& msiexec /i "& D:\LoadGeneratorsetup\HP_LoadGenerator.msi" /qb /l*vx "& D:\LoadGeneratorsetup\Logs\InstallationLogs"+"_"+(Get-Date -Format "yyyy-MM-dd-hh-mm-s")+".txt"

You have two options, either set the log path to a variable or just bracket the path:

1 - Set to variable

$logfile = "D:\LoadGeneratorsetup\Logs\InstallationLogs" + "_" + (Get-Date -Format "yyyy-MM-dd-hh-mm-s") + ".txt"
msiexec /i "D:\LoadGeneratorsetup\HP_LoadGenerator.msi" /qb /l*vx $logfile

2 - Bracket the path

msiexec /i "D:\LoadGeneratorsetup\HP_LoadGenerator.msi" /qb /l*vx ("D:\LoadGeneratorsetup\Logs\InstallationLogs" + "_" + (Get-Date -Format "yyyy-MM-dd-hh-mm-s") + ".txt")

I am assuming that the command is just not evaluating the log path before running the command.

I want to alert you to the Windows Installer PowerShell Module on github.com. Scroll down on this front page for description and some samples, see releases tab for download. I haven't really tested it much, but it is from Heath Stewart - Microsoft Senior Software Engineer (github).

Brief, inline sample:

install-msiproduct .\example.msi -destination (join-path $env:ProgramFiles Example)
