Just because you cannot open an eps file doesn’t mean that it doesn’t work. Most people who work on PC doesn’t have a vector program installed on their machines, so they can’t open eps or vector files (.ai, .cwdr) if your graphic designer is asking for it, please provide it! He or she will let you know whether this is the correct version of the logo you want.
Here is another client who is not providing eps logo and who has a problem when printing, because the reds don’t match. Keep the eps logo version and provide it to the printing company, advertising agency or graphic designer that you work with. Your logo will reproduce perfectly.
