Remote install MSI package not working when logged off

Question

I've got a problem with my script I'm working on. One part of this script should remotely install a MSI package. The problem is that it only works while I'm logged in to the target servers.

Here's the code I'm using:

1st try:

Invoke-Command -ComputerName $Computer -ScriptBlock {
    cd "C:\FlexAgent"
    Start-Process msiexec.exe -ArgumentList "/i 'FlexNet Inventory Agent.msi'  /qn /l newlogfile.txt"
}

2nd try:

Invoke-Command -ComputerName $Computer -ScriptBlock {
    cd "C:\FlexAgent"
    Invoke-Expression "msiexec /i 'FlexNet Inventory Agent.msi' /qn /l logfile.txt"
}

3rd try:

Invoke-Command -ComputerName $Computer -ScriptBlock {
    cd "C:\FlexAgent\"
    & msiexec /i 'FlexNet Inventory Agent.msi' /qn '/l*v' 'logfile.txt'
} 

Folder: FlexAgent:

    Directory: \\RemoteComputer\c$\FlexAgent


Mode                LastWriteTime     Length Name

-a---        08.08.2017     12:34       5350 Setup.ini 

I wasn't able to find any further information in the log files I defined or the logfiles in the event viewer. The logfiles are being created but they are empty.

Is there a way to install this MSI package unattended without the need to be logged in?

Answer 1

I just found the solution. I was able to install the MSI package remotely with the following commands:

$product= [WMICLASS]"\\$RemoteComputer\ROOT\CIMV2:win32_Product"
$product.Install("C:\FlexAgent\FlexNet Inventory Agent.msi")

It worked even when logged off.
