Document Lock Error

Not applicable

Hi, all.

I have a Question.

I want to make my document locked.

So I set the lock function through Adobe 9 Pro.

In the 'Security Menu', I chose the Thing titled "Password blah blah"

I did and opened the file through Adobe Reader.

But there was an error.

I could open the document which was locked through Adobe 9 Pro but not through Adobe Reader.

Why happened? If you know the solution, plz let me know

You will need to apply the password security in LiveCycle Designer and not through Acrobat.

See the File > Form Properties > Security in LC Designer.

Hi, Niall

Still there is an error.

I set the function as you said. But it's same.

There is no error when the file is opend by Acrobat pro 9.x

But by Acrobat Reader X, there is an error.

In detail, when I open the file, I can input the password.

And then, if the password is not correct, I can input it again.

but if the password is correct, the error message appeared.

I guess the security function is supported function but there is a kind of version issue.

Now, I'm using Acrobat Pro 9.x and Acrobat Reader X.

Have you ever uesed the security function? If so, let me know how I can set the password or set the other options.
