You could use a SQL report like in the example below:
--------------------------------------------------------------------------------------------------------------
select VCOM.[Guid], VCOM.[Name] 'Computername', IIFD.[Name] 'Filename', IIFD.[Path] 'Filepath' from Inv_Installed_File_Details AS IIFD
join vComputer AS VCOM
on IIFD.[_ResourceGuid] = VCOM.[Guid]
where IIFD.[Name] LIKE 'winword.exe'
and IIFD.[Path] LIKE 'C:\Program Files\%'
-------------------------------------------------------------------------------
if its another file extension you need the make changes in Inventory Solution to include the file extension.
