I have repeatedly tried installing Dreamweaver CS6 (using iMac with Mountain Lion), but each attempt leads to a failure message. A log gives 6 error messages (DF006, DF027, DWO63, and three DWO50). Any ideas why this is happening? Thanks.
It is difficult to say without being able to review the installation log. I would recommend following the directions in Troubleshoot with install logs | CS5, CS5.5, CS6 - http://helpx.adobe.com/creative-suite/kb/troubleshoot-install-logs-cs5 -cs5.html. It includes details on how to locate your installation log, locate the error messages, and look them up to determine the correct solution.
Alternately you can also try running the Adobe Support Advisor - http://www.adobe.com/support/loganalyzer/ to review your installation log.
