Detection Method using PowerShell not working using True or False

Question

Hi,

I am trying to deploy X64 Version of Teams and even though the below script for my detection method is outputting False it says the machine is already compliant in SCCM. This is a user based installation and I ran the script under the user context on the PC and the result was False but SCCM reports already compliant. Is there an issue when using a detection method like this that results in a true or false?

if (Test-Path $("${Env:LOCALAPPDATA}"+"\Microsoft\Teams\current\Teams.exe"))
   {
$teamsexecutable = get-item ("${Env:LOCALAPPDATA}"+"\Microsoft\Teams\current\Teams.exe")
if (!($teamsexecutable.length -eq 90941720)){
$teamscurrentversion = ([System.Diagnostics.FileVersionInfo]::GetVersionInfo($teamsexecutable)).ProductVersion 
[version]::Parse("$teamscurrentversion") -ge [version]::Parse("1.4.00.2879")
}
}

Hi,

According to this article, if script is used, both STDOUT and STDERR should be empty when application is regarded as "not installed"

https://learn.microsoft.com/en-us/previous-versions/system-center/system-center-2012-R2/gg682159(v=technet.10)#to-use-a-custom-script-to-determine-the-presence-of-a-deployment-type

I've changed the script slightly and you may have a try to see if it works.

 if (Test-Path $("${Env:LOCALAPPDATA}"+"\Microsoft\Teams\current\Teams.exe"))  
 {  
	 $teamsexecutable = get-item ("${Env:LOCALAPPDATA}"+"\Microsoft\Teams\current\Teams.exe")  
	 if (!($teamsexecutable.length -eq 90941720))  
	 {  
		 $teamscurrentversion = ([System.Diagnostics.FileVersionInfo]::GetVersionInfo($teamsexecutable)).ProductVersion   
		 if ([version]::Parse($teamscurrentversion) -ge [version]::Parse("1.4.00.2879"))  
		 {  
			write-host "installed"  
		 }  
		 else  
		 {  
		 }  
	 }  
 }
