Ever seen the following or a similar sentence, usually on a government site? You will need Adobe Reader to download this file.
This is not the result of an Adobe sponsorship. It’s a case of trying to be responsible plus ignorance. The intension is OK — you are trying to warn the downloader that the file in question is a PDF file — but please get with the time. It’s equivalent to This site is best viewed in a 1024x768 resolution, if you’re old enough to remember that. Everyone can open PDF files now. All operating systems come with standard software to do so, and even browsers themselves display PDFs seamlessly. Besides outdated, the message is simply false. One does not need Adobe Reader to open a PDF file.
