Use Powershell to Find Adobe Flash Version

Hello all!! Wanted to put up a post about a quick and dirty script that I wrote to check the Flash version on machines in a domain.

This can be run on all computers in the domain or you could specify the OU to search. This script will output to a tab delimited file named get_flash_version_output.txt by default but you can specify your own output file if desired. Here's the code:

 
[CmdletBinding()]  
   
 param(  
 $searchbase = $null,  
 $output = ".\get_flash_version_output.txt"  
 )  
   
 # if the searchbase isn't specified then use the default domain of the user  
 if($searchbase -eq $null)  
 {  
   $searchbase = ([adsi]'').distinguishedName.ToString()  
 }  
   
 #load all computer objects into a variable  
 $computers = Get-ADComputer -SearchBase $searchbase -Filter * -SearchScope Subtree  
   
 #iterate through each computer object  
 foreach($computer in $computers)  
 {  
   $name = $computer.name  
   
   # test to be sure you can communicate with the machine, ignoring any errors  
   if(Test-Connection $name -count 1 -ErrorAction SilentlyContinue)  
   {  
     # file that we will be querying for the version  
     $filename = "\\$name\c$\windows\system32\macromed\flash\flash*.ocx"  
       
     # test the path to be sure it exists before trying to check the version  
     if(Test-Path $filename)  
     {  
       $file = get-item $filename  
       $version = $file.versionInfo.fileversion -replace ",", "."  
     }  
     else  
     {  
       $version = "Not Installed"  
     }  
     write-verbose "$name`t$version"  
     "$name`t$version" | out-file -append $output  
   }  
   else  
   {  
     write-verbose "$name`tOffline"  
     "$name`tOffline" | out-file -Append $output  
   }  
 }  

Generic execution which will iterate through your whole domain and output to get_flash_version_output.txt

PS C:\> .\get_flash_version.ps1


Execution specifying a specific searchbase within Active Directory

PS C:\> .\get_flash_version.ps1 -searchbase "dc=Your,dc=Domain"


Put it all together -> use searchbase, verbose output, and write to a different output file

PS C:\> .\get_flash_version.ps1 -searchbase "dc=Your,dc=Domain" -verbose -output test.txt


Another feature I'd like to add is maybe have it grab the current version of Flash from HERE and let you know if you need to upgrade or not.

But that is for another time….
