Powershell script to find Office version on multiple PC's not working- Please Help?

Question

Hello!
I am about to go mad with this script. Can you help?
I am trying to search the PC’s on my domain for what office version they are running. (I am looking for any PC’s that still have Office 2003 installed).
Here is my script:
foreach ($computer in (Get-Content
PClist.txt)) {
  $version = 0
  $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $computer)
  $reg.OpenSubKey('software\Microsoft\Office').GetSubKeyNames()
|% {
    if ($_ -match '(\d+)\.')
      if ([int]$matches[1] -gt $version)
        $version = $matches[1] 
  if ($version)
      "$computer
: found $version" 
    else {
      "Could
not find version for $computer" 
It runs, but returns bad results. PC’s I know to have 2003, say they have version 13 (2007), and PC’s I know to have 2010 are showing up with version 11 (2003). Some PC’s report correctly.
Also, some PC's from PClist.txt are not even turned on, but are returning info. Weird.
Do you have any idea what I am doing wrong?
ANY help would be really appreciated.
Thanks in advance for any help you can give!

That is easy.  YOu cannot deteermine the installed verion that way.  THe key will have keys for all versions that have ever been installed.  I f you have installed a viewer that is newer then the newest key will be there.
Try this and ytou will see waht I mean
Get-Content PClist.txt |
    ForEach-Object{
        $reg=[Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $_)
        $reg.OpenSubKey('software\Microsoft\Office').GetSubKeyNames() |% {$_}
