Extracting previous version of Events4.ntf

I am having issues with the mail notification not working in 6.5.4. I have searched and found that come people claim that the Events4.ntf file does not work correctly in versions newer than 6.0.How can I extract or find this single file from a 6.0 install disk, or is there another way I can find it to overwrite the version on our server? We installed fresh with 6.5.2 and do not have the older version to replace it with.

Thanks
