I´m trying to open some pdf files, with no changes I already worked in them for months, and this message appears
Unable to read the form. Do not save and exit the program as it might cause data corruption or
loss. The form can only be edited using Adobe Reader software.
I reinstalled the Adobe Reader DC, and have the Adobe Acrobat DC sotfware installed.
The only specific feature of the non-openable files is that they are forms.
Any idea about how to solve this issue?
Thank you in advance!
