Powershell Script Compare File Array Result Version to Be Removed Issues

Question

Wrecking my logic circuits as I can't comprehend Powershell with some .NET thrown together for this compare file array results. From the array results, script is then to compare each results file version against a set version and then to delete the file if is below/not equal to the set version. I tried to use sample Comparing file versions in Powershell but it I cannot find the output issue as to why the behavior works on a Windows Server 2019 vs a Windows 10 Enterprise. Deleting old profile Teams.exe data from the MS Teams Machine Wide crap. Your assistance will be most appreciated!

My script deploys through MS Endpoint/SCCM

$TeamsPath = 'C:\Users*\AppData\Local\Microsoft\Teams\current\Teams.exe'

$FileVersion = @(Get-ChildItem -Path $TeamsPath -Recurse -Force)

foreach ($TeamsPath in $FileVersion){
    $ProductVersion = [System.Diagnostics.FileVersionInfo]::GetVersionInfo($TeamsPath).ProductVersion
    $TargetVersion = [System.Version]::Parse("1.3.0.13000")

    if ($ProductVersion -le $TargetVersion){
    Remove-Item -Path $TeamsPath.Directory -Force -Recurse
    }
}

Revised with the original answer to have a proper and cleaner routine to delete/uninstall Teams from old user profiles

$TeamsPath = 'C:\Users\*\AppData\Local\Microsoft\Teams'

$TargetVersion = [version] '1.3.0.13000'

Get-ChildItem -Path $TeamsPath -Filter "Teams.exe" -Force -Recurse | 
  ForEach-Object {
  if ([version] $_.VersionInfo.ProductVersion -le $TargetVersion) {
  
  $UpdateRun = Split-Path $_.DirectoryName 
  
  Start-Process -FilePath "$UpdateRun\Update.exe" -ArgumentList "--uninstall /s" -PassThru -Wait -ErrorAction STOP
  
  #Remove-Item -LiteralPath $_.DirectoryName  -Force -Recurse -WhatIf
  }
}

The problems with your code:

(This may be posting artifact) You're looking to loop over all users' AppData folders, so the wildcard path must start with 'C:\Users\*\... not C:\Users*\... - that is, * must be its own path component.
There's no need to call [System.Diagnostics.FileVersionInfo]::GetVersionInfo($TeamsPath), because the .VersionInfo ETS property that PowerShell decorates the System.IO.FileInfo instances with performs exactly that call behind the scenes.
The .ProductVersion property contains a string representation of a version number; if you use it as the LHS of your -le comparison, string comparison is performed (the [version] (System.Version) RHS is then coerced to a string too).

The following is a streamlined version of your code with the problems corrected:

$teamsPath = 'C:\Users\*\AppData\Local\Microsoft\Teams\current\Teams.exe'
$targetVersion = [version] '1.3.0.13000'

Get-ChildItem -Path $teamsPath -Force | 
  ForEach-Object {
    if ([version] $_.VersionInfo.ProductVersion -le $targetVersion) {
      Remove-Item -LiteralPath $_.DirectoryName  -Force -Recurse -WhatIf
    }
  }

^{Note: The -WhatIf common parameter in the command above previews the operation. Remove -WhatIf once you're sure the operation will do what you want.}

Uninstall command for Teams revised answer with the changes that @mklement0 helped on. $UpdateRun = Split-Path $_.DirectoryName ` Start-Process -FilePath "$UpdateRun\Update.exe" -ArgumentList "--uninstall /s" -PassThru -Wait -ErrorAction STOP`
