Error: All or part of the selection has no avilable font system. You cannot add or delete text using the currently selected font.
Adobe’s Acrobat Professional along with pretty much every piece of software that Adobe makes is criticized for it’s lack of user-friendliness and intuitiveness. If you are trying to edit a PDF document in Adobe Acrobat Professional by using the TouchUp Text Tool, you may have encountered an error when you try to edit or delete the text. The error you get is:
All or part of the selection has no available font system. You cannot add or delete text using the currently selected fonts.
Frankly, in this case the error is useful as it gives you some hint as to what the problem might be. The problem here is that the font used in the PDF document that you are trying to edit is not one of the system fonts. In order to fix the problem, you need to use a font that is recognized by the system.
Highlight the text you are trying to delete or edit and then right-click and select Properties. Click on the Text tab. You will notice that on the Text tab the Permissions section says “No system font available.” Change the font to a system font. For example, if the text used is Myriad-Roman, from the Font drop-down button change it to MyriadPro-Regular. You will notice the Permissions section now says “Can embed font.” Once you close the Properties window, you should be able to delete or edit the text as necessary.
