I would suggest to update Adobe Application manager from
Windows : http://www.adobe.com/support/downloads/detail.jsp?ftpID=4773
MAC: http://www.adobe.com/support/downloads/detail.jsp?ftpID=4774
then try to install the update if still you are not able to update software and getting same error then uninstall all the Adobe software selecting remove prefernces.
After uninstalling the software run the Adobe Cleaner tool(http://www.adobe.com/support/contact/cscleanertool.html) and remove the leftovers.
