One of the features I was really looking forward to in CS6 was creating fillable forms with ONE application. I created a form following the step by step instructions in classroom in a book for CS6. When I opened the exported form in Reader X, I get a "This operation is not permitted" error. I opened the completed "end" document in the lesson to make sure I didn't commit an error, and I got the same message when exporting. I have looked for places in menus to modify security restrictions and I can't find any. I installed the updates and that didn't solve the issue.
I saw one solution posted which is to open the document in Acrobat, then do a "save as" option. Is there anything we can do that doesn't involve buying additional software? If this is not the case, then Adobe seriously needs to change its training and advertising about this functionality.
