Powershell Output does not display when run on remote PC

I wrote a simple script to display installed programs. It works on the local machine just fine - grabs the programs, lists them alphabetically, great. When I try to run it on a remote PC, the script finishes but there is no output. No error, but nothing displayed. I tried putting Write-Host in various places, but no joy. I would like to be able to retrieve this information without having to write it to a file on the local machine, and then open the file to read the info. Any hints? Also not sure if the invoke-command is needed.


$Computername = Read-Host -prompt ("Which PC would you like to Inventory installed software on?")
$Credential = Read-Host -prompt ("What domain and username would you like to Authenticate with?")
$s = New-PSSession -ComputerName $Computername -Credential $Credential
Invoke-Command -Session $s -ScriptBlock {Get-WMIObject -Class Win32_Product -Computername $Computername | Sort name | Format-Wide -Column 1 -passthru}
