Using CommonLook PDF

Once CommonLook PDF has been installed and registered, you’re ready to begin using it!

Please refer to the CommonLook PDF User’s Guide for additional help using the software.  Hint:  You may find the “Quick Start Guide” particularly helpful.

Open a tagged PDF in Adobe Acrobat and, in the toolbar at the top, choose “Plug-Ins.”  In the menu that opens, choose “CommonLook” and then choose “CommonLook PDF GlobalAccess.”

If the PDF is not tagged, an error message, like the one pictured below, will appear, stating that the document is untagged and that you should add tags in Acrobat before opening CommonLook.

If CommonLook Won’t Open and the Document Has Tags

When opening CommonLook PDF, the software will “ping” the server to see if there are any available “seats” for the licensing key.  If there are “seats” available, CommonLook will open.  If there aren’t any “seats” available then an error message, like the one below, will be displayed, telling the user that CommonLook is unable to connect to the server and requesting that the user try again later.
