I could not find a report in NS6 that is called: Computers With Selected Application Installed. What is the path in the NS console?
Try this report for finding Office:
SELECT DISTINCT
p.[name] [Office Name],
COUNT (*) [Count]
FROM inv_aex_os_add_remove_programs p
JOIN vcomputer c ON c.guid = p._resourceguid
WHERE (p.[Name] = 'Microsoft Office XP Professional with FrontPage'
OR p.[Name] = 'Microsoft Office XP Professional'
OR p.[Name] = 'Microsoft Office XP Standard'
OR p.[Name] = 'Microsoft Office Professional Edition 2003'
OR p.[Name] = 'Microsoft Office Standard Edition 2003'
OR p.[Name] = 'Microsoft Office Professional Plus 2007'
OR p.[Name] = 'Microsoft Office Enterprise 2007'
)
GROUP BY p.[name]
Order BY COUNT (*)
