I am using Adobe Acrobat Reader 9.3.0.
Some users at my company are having problems when opening pdf's that have fillable fields in them.
They get an error when opening the document:
And following that error:
This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document.
However this error is not computer related error, if I log on to a computer as user1 (non local admin user) the document opens fine and I am able to fill in the forms), then I log on as user2 (local administrator rights) and the document gives me these errors.
Also if I go to Edit/Preferences/Security logged in as a usere that is getting the error then I get this error additionaly:
Your signature appearance file appears to be corrupt. Would you like to delete this file? Acrobat error. Access denied
When I browse to %appdata%\roaming\adobe\acrobat\9.0\security\ then there is no appearances.acrodata there to delete.
The system time is correct.
the forms seems to work when we use IE to open the form instead of Acrobat Reader program itself.
We have been using that "solution" for now.
I haven't tested if Reader X solves this problem.
My organization is having this issue as well. At first we thought it has something to do with Windows 7, but none of our engineers were able to troubleshoot and determine the root cause. I am curious to see what the response will be now that other organzations have reported a similiar issue.
