When you try to install an update for Adobe Acrobat 8 Professional on Mac OS, the update installer returns the following error:
"Update failed. The patch has failed because the application has been modified since it was originally installed (for example, plug-ins may have been disabled). Please go to the Adobe support website for more information regarding how to re-enable disabled components prior to installing the patch. Or, you can install and reinstall the application, and then reinstall the patch."
