This means that you are trying to edit a scanned document. I don't have Acrobat Standard, so I don't know exactly what tools are available in Standard. In Acrobat Pro, there are two different things you could do to make this document editable (both require running OCR):
- Tools>Document Processing>Optimize Scanned Document - make sure that you select to OCR the document
- Tools>Recognize Text>In this document
In both cases, make sure that you select the "ClearScan" output format. Otherwise you only end up with the image of the scanned page, with all recognized text "hidden behind" the image. ClearScan will actually convert your text to individual glyphs that can be edited.
