Need Help Uninstalling Codec

Hello, I'm going to try to keep this as short as possible. I installed Avid Quicktime Codecs in order to be able to play DNxHD files in quicktime. However after doing that, it 1) still can't read them, and 2) now won't play .AVI which it previously did with the help of a thing called Perian that I downloaded a while ago. Now, all I want to do is get rid of this, so It can go back to the way it was, however I have no idea how to do this. I can't find the file anywhere, however when I went to "About this Mac", then "System Report", then "Software" and then "Installations I can see them right there. The two I want to get rid of are "Avid Quicktime Codecs LE" and "AvidCodecsLE_Root". So if anyone can help me I'd really appreciate it.

Incase any of this info is needed :

iMac 21.5in" Mid 2011

2.5 GHz Intel Core i5

12 GB 1333 MHz DDR3

AMD Radeon HD 6750M 512 MB

(I really hope this made sense. Also, sorry if this isn't the correct place to post this.)

Thank you!

iMac, OS X El Capitan (10.11)

Hey AJ392, did you ever find a new solution to the uninstall? I'm trying to get through the exact same problems, getting rid of the codecs. Thanks!

If you have an uninstaller or can obtain one from Avid, then use it to get rid of the files.
If you know where they are installed then navigate there, select the two files, put them into the Trash, Empty Trash and/or restart.
If you don't know where they are:

Basics for Uninstalling Software

Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.

Some applications may install an uninstaller program that can be used to remove the application. If you cannot find the uninstaller then you could download the freeware, Easy Find, to locate files that need to be removed. The places you need to search include:

/Home/Library/Applications Support/ folder. Check if the application has created a folder then delete the folder that's in the Applications Support folder.

Applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder or the /Home/Library/StartupItems/ folder. Log In Items are set in the Users & Groups preferences. Open it inSystem Preferences, then click on the LogIn Items tab. Select the item from the list and click on the Delete [-] button to remove it.

Some software use startup daemons or agents. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.

Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.

There are many utilities that can uninstall applications. Here is a selection:

AppZapper

AppDelete

Hazel

AppCleaner

CleanApp

iTrash

AppBolish

AppUninstaller

Uninstaller

Hi, there thank you for your quick response. I have no idea where the files are and when I downloaded it, there was no uninstaller or folder that download, it just popped up and said installation finished. So, it's like something installed, but I have no idea what or where.

I tried using both Easy Find and AppZapper, and they were nowhere to be found, which doesn't make much sense, since it says they are somewhere in the system report.

I was able to download a newer version of the Avid codec, which even though it is still not reading .AVI files, it is converting them again, which it wasn't before, so it's kind of a temporary fix.

Thanks for the reply Kappy!
