I have an email with an attachment that requires a password the open.  I can open the file but embedded in the attachment is another attachment.  When I double click attachment I get the following error message.  Acrobat cannot open the file attachment because your PDF file attachment settings do not allow this file type to be opened.

What is your operating system?  Reader version?

What is the file type of these attachments?

OS: windows 7

Adobe XI

File is PDF

You would need to make a change to your registry; see http://www.adobe.com/devnet-docs/acrobatetk/tools/AppSec/attachments.html

Basically you would need to add the .pdf with the permission 2.

Let us know if you need help with that.  Either way, make sure to create a System Restore Point before editing the registry.

The above should read: need to add or modify the .pdf file extension...

I drive my computer like my car...I dont known whats on the bonnet.  The computer has always opened the documents and I have gone to computer shops for something to down load to fix the problem but get the run around. Why cannot ADOBE provide an automatic fixer in their programs.  What can the dummies do to fix it.
