I downloaded and installed CS6 Master Collection Trial, but only Audition, SpeedGrade, Air Apple iOS support, Dreamweaver, and Acrobate X Pro installed. Flash Builder, Photoshop (64-bit), Premiere, Encore, After Effects, Flash Professional, Illustrator, Photoshop, Illustrator (64-bit), Firworks, InDesign, and Prelude did not install. There was an error summary that had literally 100's of different errors. What now?
You will want to review your installation logs to determine the errors you are receiving and what steps to perform to resolve those issues. You can find details on how to locate and review your installation logs at Troubleshoot with install logs | CS5, CS5.5, CS6 - http://helpx.adobe.com/creative-suite/kb/troubleshoot-install-logs-cs5-cs5.html.
