Help with Query

Hi,

A couple things with the query pasted below. It was from a query that someone provided to me that worked in 7.0 but not in 7.1. I am trying to produce a report of all systems with Firefox.

The query in its present form returns results, but I am not sure as to how accurate it is. I say this because upon closer examination of a couple systems within Resource Manager it appears Altiris has entries for prior versions of Firefox that were upgraded over time. I don't know if this in fact the case since I can not see the W7 Add/Remove Programs list on some of these computers. I am not sure if I have inaccurate inventory records or if in fact something else is going on. I assume I want to query the Inv_AddRemoveProgram table or should I be using another table??

Also, I'd like to clean up the results returned so something like Mozilla Firefox 20.0.1 (x86 en-US) is simply Mozilla Firefox. Anything after the word Firefox should be trimmed to keep this clean. Do I need to do a right trim or how would I clean up the results returned?

SELECT DISTINCT
vCom.[Name] as [Computer Name]
,ac.[Last Logon User]
,arp.[DisplayName] AS [Product Name]
,arp.[DisplayVersion] AS [Product Version]
,vCom.[OS Name] AS [Operating System]
,vCom.[OS Revision] AS [Service Pack]
FROM
CollectionMembership cm
INNER JOIN
vComputer vCom
ON cm.[ResourceGuid] = vCom.[Guid]
INNER JOIN
Inv_Aex_AC_TCPIP ip
ON vCom.[Guid] = ip.[_ResourceGuid]
INNER JOIN
vCollection vColl
ON cm.[CollectionGuid] = vColl.[Guid]
INNER JOIN
Inv_AeX_AC_Identification ac
on ac.[_ResourceGuid] = vCom.[Guid]
INNER JOIN
Inv_AddRemoveProgram arp
ON arp.[_ResourceGuid] = vCom.[Guid]
LEFT JOIN
vHWComputerSystem cs
ON cs.[_ResourceGuid] = vCom.[Guid]
WHERE
    IsManaged =1
    and
    [Identifying Number] is Not Null
    and
    vCom.[OS Name] not like '%windows server%'
    and
    (
        arp.[DisplayName] LIKE 'Mozilla Firefox%'
                       
    )
    
    ORDER BY vCom.[Name]

Thanks.
