Same deal. Yesterday everything was fine. Today, totally stalled on the ExporterQuicktimeHost.

Just got off the phone with Adobe support and they told me to call Apple as it is a permissions problem. That's all he could tell me even though I haven't installed anything or changed my system or updates anything.

We opened my system to the "root" user and the application opened just fine. Very annoying.

This is happening to me, too!

I tried everything from that old CS5 documentation for AE, that stuff from Todd Kopriva about firewalls and removing QuickTime components, and absolutely nothing has worked. Additionally, I've uninstalled and reinstalled everything, and trashed all relevant preferences in /Library. I've done all this from within the "root" user. I've cleared PRAM on my machine, and repaired and verified all disks involved, to no avail.

Adobe's phone support is baffled.

This has brought my work to a griding halt.

The plot thickens.

This morning, Adobe was able to get Premiere Pro working on the "root" user account, but not any other user.

I called Apple, and with them I repaired the disk permissions and repaired the disk from Lion's repair partition. I also cleared the "Caches" folder from the user Library, and tried in Safe Mode.

A senior support representative at Apple informed me that getting Premiere Pro to work on the root account wasn't helpful, because pretty much anything will work in the root account. He had me create a totally brand new administrative user account, and the application is still hanging on ExporterQuickTimeHost.bundle, so this can't be a permissions problem. This is certainly a problem with the application, because the new user account is a totally fresh environment.

I'll keep you all posted.

Please document the step by step for this process as I may have to resort to this as well for AE CS6. Keep stalling on mediacore.

Sorry, I had to let me colleague borrow my computer for something else. I'll be able to continue working on this sometime next week. I'll keep you all posted.

My colleague borrowed my computer last week. I just got it back, and the issue seems to be resolved. I can open up Premiere just fine. I'm not sure what changed, if anything, but I'm pretty sure he wasn't working on fixing this. He didn't need Premiere at all.

SUCCESS! Apple solved my problem!

Adobe told me to go back to Apple to reset access control.

Here's what Apple had me do, and this worked:

1. Shut down the computer
2. Power it on, while holding down the Option key
3. Select "Recovery HD"
4. Select the language that you want to use
5. In the menu bar, select "Utilities"
6. Open Terminal
7. Be very careful in Terminal, and type "resetpassword" [no quotation marks, no spaces]
8. Hit Enter
9. In the window that opens, select "Macintosh HD" as your disk
10. Select your user account
11. In the very bottom of this window, where it says "reset ACL," click "Reset" and let it run.
12. Close the Reset Password app.
13. Close Terminal.
14. Shut down.
15. Turn the computer on, login to your account, and Premiere, Media Encoder, or After Effects should work fine.

To everyone who encounters thread this in the future, I hope this helps!

I found a good article on "How to Repair User Level Permissions" on Snow Leopard which discusses using "reset ACL."

I tried this technique, but still no go. Premier CS6 still hangs on launch at "loading ExportQuickTimeHost.bundle." In addition, both After Effects CS6 and Adobe Media Encoder will not open.

I am dead in the water. If anyone could point me in the right direction, it would be greatly appreciated.

Thanks again,

Kevin

Read #22 by another seth (monger) from May 12, 2010.  In the Mac/Library/QuickTime folder, I began deleting odd codecs and after my first attempt, it worked.  Thanks goes to seth.

The QuickTime repair all link has all the tips we need here:  http://blogs.adobe.com/toddkopriva/2011/02/troubleshooting-quicktime-e rrors-with-after-effects.html

I tried removing all of my codecs and restarting... no good. Then I added back only the Apple codecs and restarting... still no good.

As I noted in post 17 of this thread, I have also tried the "reset ACL" suggestion from Seth. Did not work.

Kevin

Seth,

Here's the latest twist. Since removing codecs from my Mac/Library/QuickTime folder didn't work, I took a look in my username/Library/QuickTime folder and removed the two files I found there... Voila, after a restart, PP and AE will now both successfully launch!

Below are the names of the files I removed.

AC3MovieImport.component

Perian.component

I have to admit, I am not the least bit confident this is going to last. I'm just soooo greatful I wasn't in the middle of a major project.

Thanks again for your advice.

Kevin

I tried this...I renamed the file in the QuickTime directory and moved them to a subdir I called TEST...tried to resart PP ... froze again.

Do I have to DELETE the files or is renaming them enough?

I GOT IT...I went to MAC/Applications/Adobe Premiere Pro CS6/... SHOW PACKAGE CONTENTS ... look into Common/ ... then delete the import and export Quicktime bundles and everything works again.

I have don't that before.  I don't know why the files are back...what made them come back.

I have been having this issue periodically on CS5.5 and now on CS6, very frustrating. I would typically fix it by what bdaul said in #27, then I would replace the 2 QT.bundle files with the same named files from the Package Contents of the Media Encoder and that seemed to work SOMETIMES. But on CS6 the problem seemed impossible to fix. Then I found on another forum (can't remember which one) that a person said they repared their Mac HD disk permissions 3x and it worked. So I did it once, no go, then I did it 3 more consecutive times and restarted and that worked. I HOPE that is a more permanant solution! This really seems like an Adobe issue.

Also, this whole issue started to happen with CS6 as soon as I installed the PPro & Encore Functional Content. Then I immediately had the loading issue and Encore would open but freeze with the lovely beachball. The Disk Permissions has fixed both issues.

Good luck!
