First of all, here is the error message that I am trying to deal with:
"This document contained certain rights to enable special features in Adobe Reader. The document has been changed since it was created and these rights are no longer valid. Please contact the author for the original version of this document."
Software & PDF details:
Adobe Reader 8. V8.1.1
PDF Producer: Toolkit http://activepdf.com
PDF Version: 1.5 (Acrobat 6.x)
The PDF is set to with:
Filling of form fields: Allowed
After investigation I have found that:
- If I open the file by double clicking, I am able to fill in the fields and save without any problems.
- If the file is opened as a result of a software process trigger (which is what I actually want to achieve), the "Filling of form fields" is changed to "Not Allowed". This then results in the error message described above.
Also, I have another PDF with exactly the same settings as above (PDF version and Producer etc), which successfully generates as a result of the software process trigger. This file that works does not change the "Filling of Form Fields" value.
So, my question is, why would a particular PDF change the "filling of form fields" value depending on how it is opened?
