How can I get version Information for multiple computers? -Powershell - sql-server

Question

I am trying to write a script to determine whether or not a server is running MSSQLSERVER or MSSQL$* (some instance of SQL Server) by going through a text file of server names separated by a new line. The code works for the first server and outputs the correct version and engine edition, but for all of the other servers it will only tell me whether or not they running SQL Server, and not output the version and engine edition. What am I doing wrong?
Thanks in advance for any and all help!
Clear-Host
$Name1 = "MSSQLSERVER"
$Name2 = "MSSQL$*"
$computers = Get-Content "E:\computers.txt"
$saveAs = 'E:\SQL_Report.txt'
foreach ($computer in $computers) {
try{
$Service1 = Invoke-Command -ComputerName $computer {Get-Service MSSQLSERVER}
$Service2 = Invoke-Command -ComputerName $computer {Get-Service MSSQL$*}
if($Service1 -Match $Name1 -Or $Service2 -Match $Name2){
"$computer Running MSSQL"
[reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | out-null
$srv = New-Object "Microsoft.SqlServer.Management.Smo.Server" "$computer"
$srv.Version
$srv.EngineEdition
}
else{
"$computer Not running MSSQL"
}
}
catch{
"$computer, Not Accessable, $_"
continue
}
}
Here is an example of current output:
