Over at the Ruby on Windows blog, David posted an article about how the latest versions of Office allow for saving files as PDF. Which prompted me to ask how you can find out what the versions are, since Office 2003 apps don’t have this option. So in between watching the AFC Championship game, I figured it out and came up with the following program:

require 'win32ole'

xl = WIN32OLE.new('Excel.Application')
xl.visible = false

ver = nil
case xl.Version
   when "12.0"
     ver = "Excel 2007"
   when "11.0"
     ver = "Excel 2003"
   else
     ver = "{Unknown Version => #{xl.Version}}"
end
puts "     Excel Version: #{ver}"
xl.Quit

word = WIN32OLE.new('Word.Application')
word.visible = false
ver = nil
case word.Version
   when "12.0"
     ver = "Word 2007"
   when "11.0"
     ver = "Word 2003"
   else
     ver = "{Unknown Version => #{word.Version}}"
end
puts "      Word Version: #{ver}"
word.Quit

ppt = WIN32OLE.new('Powerpoint.Application')
#ppt.visible = false    ## Powerpoint 2007 does not allow itself to be hidden?!?
ver = nil
case ppt.Version
   when "12.0"
     ver = "Powerpoint 2007"
   when "11.0"
     ver = "Powerpoint 2003"
   else
     ver = "{Unknown Version => #{ppt.Version}}"
end
puts "Powerpoint Version: #{ver}"
ppt.Quit

ol = WIN32OLE.new('Outlook.Application')
#ol.visible = false
ver = nil
## Outlook seems to tack on a build number
tt = ol.Version.slice(0,4)
case tt
   when "12.0"
     ver = "Outlook 2007"
   when "11.0"
     ver = "Outlook 2003"
   else
     ver = "{Unknown Version => #{ol.Version}}"
end
puts "   Outlook Version: #{ver}"
ol.Quit
