I have installed the Acrobat Standard 8.1.2. I made a configuration into the program and now unable to undo those changes . It begins when I installed the voice recognition for Microsoft Word. After that I started the Acrobat and it came up with the Accessibility Setup Assistant. I didn't really aware about this what going wrong with this . Now, whenever I pull up a new one document then I am getting a window which states that "Content Preparation Progress". In the window, it states that "Please wait while the document is being prepared for" . Then if I browse up the PDF of something I scanned, I received a window known as "Scanned Page Alert". The message is "This page contains only an image of a scanned page. I didn't got this type of issues before... Please help me out from this problem !!! please ..
