See http://www.catb.org/esr/faqs/smart-questions.html#beprecise Trying your example on Windows 7 Ruby 1.9.3 I get Win32_Test.rb:3:in `initialize': unknown OLE server: `MSComDlg.CommonDialog' (WIN32OLERuntimeError) This suggests that component is not installed on my machine. Even if it was installed, Google suggests there would be a Microsoft component licensing issue: http://dutchgemini.wordpress.com/2010/12/23/vba-cannot-create-mscomdlg-comm= ondialog-activex/ If you insist on solving your problem by using native Windows dialogs, an alternative to an OLE component would be to access the Win32 API directly: http://www.ruby-doc.org/docs/ProgrammingRuby/html/win32.html#S3 See Win32 GetOpenFileName(): http://msdn.microsoft.com/en-us/library/ms646927%28VS.85%29.aspx http://msdn.microsoft.com/en-us/library/ms646829(v=3Dvs.85).aspx#open_file GetOpenFileName() is deprecated but is probably easier to use than the alternative. However, it will involve packing the OPENFILENAME members, as in the example I linked to at the start of my email.
