Unable to play .avi files after upgrading Perian
![qa-featured](https://www.techyv.com/sites/default/users/superadmin/qa-featured-300x270.png)
I am running Mac OS X Lion with QuickTime Player 7 and Perian for Mac. I used to play .avi files without problem. But today when I updated Perian, I started having issues on playing .avi files. When I tried to roll back to the previous version, I was still unable to play the file. I have searched everywhere for possible solutions but I was unlucky to get one. How can I fix this?

The document " .avi" could not be opened. A required codec isn't available.
To see if additional software is available that will enable QuickTime Player to open the movie,click Tell me more.
