Report to show major Internet Explorer version

Question

There's many posts relating to an accurate way of reporting on which version of Internet Explorer is being used by a PC. It is not made easy by the fact that some versions are recorded in Add/Remove programs, while other versions aren't, and there
seems to be some dependency on whether it was installed with the O/S or later upgraded via WSUS etc etc.
Here's the report I've creating (using file versions of iexplore.exe) - which works OK, but what I'd really like is if I could 'roll up' the results into a count of major versions. So instead of having seperate lines for 7.00.6000.16386 and 7.00.6000.17055
(for instance), it just gives me one line for v7, one for v8 etc.
Any ideas how this could be achieved?
select
    FileName,
    FileVersion,
    @CollID as CollectionID,
    Count (Distinct SF.ResourceID)
From
    dbo.v_GS_SoftwareFile SF
JOIN v_FullCollectionMembership fcm on SF.ResourceID=fcm.ResourceID
Where
    FileName = 'iexplore.exe'
and
    FilePath like '%Internet Explorer%'
and fcm.CollectionID=@CollID
Group by
    FileName, FileVersion
Order by
    FileVersion

Plagiarized a bit--showing OS (trying to limit to only major version of that--could have used a CASE statement, I guess) as we have a requirement to only have certain version of IE on certain OS...
select
SF.FileName AS 'FILENAME',
LEFT (OSYS.Caption0, 20) AS 'OS',
left(SF.FileVersion,2) AS 'IE MAJOR VERSION',
Count(Distinct SF.ResourceID) AS 'COUNT'
From
dbo.v_GS_SoftwareFile SF
JOIN dbo.v_R_System SYS ON SF.ResourceID = SYS.ResourceID
JOIN dbo.v_GS_OPERATING_SYSTEM OSYS ON SF.ResourceID = OSYS.ResourceID
Where
SF.FileName = 'iexplore.exe'
and SF.FilePath like '%Internet Explorer%'
AND SYS.Client0 = '1'
AND SYS.Obsolete0 = '0'
AND SYS.Operating_System_Name_and0 LIKE '%workstation%'
AND OSYS.Caption0 IS NOT NULL
AND OSYS.Caption0 NOT LIKE '%(R)%'
AND OSYS.Caption0 NOT LIKE '%embedded%'
Group by
SF.FileName,
LEFT (OSYS.Caption0, 20),
left(SF.FileVersion,2)
Order by
CASE left(SF.FileVersion,2) WHEN '6.' THEN 0
WHEN '7.' THEN 1
WHEN '8.' THEN 2
WHEN '9.' THEN 3
WHEN '10' THEN 4
WHEN '11' THEN 5
END
