Just make sure that you don't need any of the extras that come with the Ultimate subscription to make change you need - it's very unlikely you do. In your email, please reference this forum thread. You will be able to open it on the cheaper standard Media Composer with no problems, the ultimate subscription is the same software with extra features. Then please email me at and I can help further. Go into the Mac's Application s folder, find Media Composer, and drag its icon into the Dock. It is actually installing fine, it's just that the icon for Media Composer is not isntalling correctly in the Dock.

Should I not be downloading the other things included in the installer? Is there anything else to be checking to make this install properly? I deleted the previous version of AVID I downloaded and tried to install a few weeks ago. If you are, the next thing to try is when you double click Media Composer to open it, immediately hold down the 'w' key, which should bring up the box that asks how you want to activate Media Composer, or if you want to run in trial mode. I'm running 12.3 and the AVID version I just downloaded is 21.4 (redeployed).
