How to pass arguments to MSI file with PowerShell - powershell

Question

I've read that you can pass arguments to a .msi file, but I have no idea how to do it correctly. I've tried the following, where $ArgumentList is an array.
$ArgumentList = #("/i .\NSClient v67.msi", "/norestart", "/quiet", "/l*v '$directory'", "token=$token", "host=$_host", "mode=$mode")
Start-Process "msiexec" -ArgumentList $ArgumentList -Wait -NoNewWindow
This is part of my script, where I'm trying to install NetSkope on my machine by executing a command.
In theory, the command should look like msiexec /i "NSClient v67.msi" token=loremipsum host=bryan.goskope.com mode=peruserconfig /norestart /quiet /l*v "C:\Temp\NetskopeInstallation.log.
#Find file path
$rawPath = Invoke-Expression -Command 'C:\Windows\System32\WHERE /r C:\Users\ /f NSClient*.msi'
#Extract the directory
$filePath = Invoke-Expression -Command "cmd.exe --% /c FOR /f ""tokens=1"" %A IN ($rawPath) DO (ECHO
'%~dpA')"
#Cast $filePath to work with string methods
$filePath = Out-String -InputObject $filePath
$filePath = $filePath.split("'")[1]
Invoke-Expression -Command "cmd.exe --% /c cd $filePath"
$ArgumentList = #("/i .\NSClient v67.msi", "/norestart", "/quiet", "/l*v '$directory'",
"token=$token", "host=$_host", "mode=$mode")
Start-Process "msiexec" -ArgumentList $ArgumentList -Wait -NoNewWindow

Answer 1

I would also recommend using the Powershell MSI Module
Concerning Start-Process:
-Argumentlist expects string as a type. I don't think you can just pass an array.
You also need to surround the parameters that require a space with escaped double quotes. The escape character is powershell is the grave-accent(`).
Another problem is that the variable $directory will never be expanded, because it is surrounded with single quotes. You need to remove those.
The following should work for your example, but I personally would just remove the space in the file name, since you don't need to do weird stuff with escaping.
Without escaping:
$ArgumentList = "/i .\NSClientv67.msi /norestart /quiet /l*v $directory token=$token host=$_host mode=$mode"
With escaping:
$ArgumentList = "/i `".\NSClient v67.msi`" /norestart /quiet /l*v $directory token=$token host=$_host mode=$mode"

Here's a slightly different syntax:
$MSIArguments = #(
"/x"
"`"C:\path with spaces\test.msi`""
"/qb"
"/norestart"
"/l*v"
"`"C:\path with spaces\test.log`""
)
Start-Process "msiexec.exe" -ArgumentList $MSIArguments -Wait -NoNewWindow
