How to reinstall Quicktime

Recently having issues with Quicktime (10.2), it tends to hang for a few minutes at a time constantly through a movie. How can I install a new copy of the software, can't load a new version for it detects the existing copy, and can't delete the original version either?

QuickTime X for Lion is not a separate download. If it needs to be reinstalled, you'd have to reinstall Mac OS X. A could of things you can try, though:
- check for any third-party codecs or other plugins and either update or (preferably) delete them and see if that makes any difference
- run Activity Monitor, set it to show all processes, and see if there's anything that's popping up that's using a signficant amount of CPU time at the time these stalls happen
- try the movies with a different player such as VLC Media Player and see if similar stalls occur. If they do, then the probably is most likely with the movie files, not with QuickTime.
The above suggestions presume that these movies are local files, not something being streamed from another system or site.
Hope this helps.

How to reinstall Quicktime Plugin for Safari in Mac

I recently deleted all plugins for Safari in Mac, in order to fix unusual (slow at times) speed of safari.
When I watch a trailer at apple.com/trailers, it works fine.
However, when I try to watch a HD version of the trailer, I get this message
"The document “stone-fte1_480p.mov” could not be opened. "
Please advise how to reinstall the necessary Quicktime plugin in order for it work fine like before.

Hi and welcome....
Insert your install disc or your Snow Leopard disc. It should open when it mounts the disc on your Desktop. If not, double click the icon.
Open the Optional Installs folder then the Optional Installs.mpkg folder.
Go through the install process. When you get to Installation Type / Custom Install
Select QuickTime 7
Click Continue. Restart your Mac. Then repair permissions.
Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.
If you don't have your install disc handy, you can download the QT software here. http://support.apple.com/kb/DL923

Does anyone know how to reinstall quicktime on an older g-5 running 10.4.11

i was getting error-50 after updating safari/firefox and most wmv files would not open. i deleted quicktime , emptied it from trash, did a restart, and tried to reinstall several versions of quicktime from apple with zero luck ... anyone out there know what i need to do to get quicktime back on this old G5?

Hi, Kirk,
It can, actually. A full installer of 7.6.4 can still be found here:
http://support.apple.com/kb/DL838
and it will reinstall QT Player; I peeled the package apart with Pacifist to be certain.
Good to know about the problem with the latest F4M versions and 10.4. Thanks.
Cheers.

How to reinstall QuickTime X

I wanted to buy QT 7 Pro and tried to download it. I didn't realise QT 7 was already on my Mac 10.6.6. I couldn't do it, and therefore deleted QT X, thinking that was the solution. Now I want QT X back, but I cannot find it on my installation disc, only QT 7? How do I get it back?

Use Pacifist to extract it from the DVD, and then run the Mac OS X 10.6.6 combo updater.

How do I reinstall Quicktime X or 7?

Hello!
I am running 10.6.8 on an iMac with a 3.2 GHz Intel Core i3.
I wanted to use Quicktime 7 Pro instead of Quicktime X.
QT7 would not install with QTX present, so I deleted QTX by putting it in the trash.
This did not fully uninstall QTX, and now I am unable to install any version of Quicktime my computer.
How can I reactivate or uninstall QTX so that I can have some type of Quicktime program in use?
I don't care about which version of Quicktime it is at this point, I just need one of them to be present.
Thanks ever so much with any help you are able to provide.

Actually, you can probably use an App called Pacifist to reinstall Quicktime X.

How can I reinstall QuickTime Pro on Win7?

I purchased QuickTime Pro in September. Then this week, I upgraded my PC from Windows XP to Windows 7. In doing so, I had to wipe out my PC's partition and re-install every program back on my PC.
This has been a relatively painless process, except for QuickTime Pro. I re-installed Quick Time 7 (the free version) on my PC but there appears to be no way to upgrade the free version of QT back to Pro without purchasing this product all over again (and I refuse to do that).
I've tried talking to Apple's technical support. They've given me directions written for previous versions of Windows, but there appears to be no instructions for how to upgrade to QT Pro if you have Windows 7.
I've been on the phone with their technical support for the past two hours and no one at Apple appears to know how I could reinstall QuickTime Pro.
I'm astonished.

Here's the link to retrieve your lost registration key http://support.apple.com/kb/HT2376
What version of QT did you have on XP? If you had QT version 6.X pro then you would have to purchase a new QT pro key for QT 7. As Apple releases complete new versions of QT they require a new pro key, updates to a version do not. In other words the pro key for QT 6 does not work with QT 7.
And if you were using QT pro 6.X you cannot revert back to that version. Because QT 6 doesn't support windows 7

How can I reinstall Quicktime X in Lion?

OK, to make a long story short, I had a new audio problem in the Quicktime X Player after installing Lion (that I oddly enough didn't have in QuickLook, QuickTime Player 7, or VLC), and I assumed a reinstallation was in order (because I also assumed I had mucked something up by trashing some "orphan" files with TrashMe). I thought I couldn't reinstall Quicktime X Player from the Lion installation package without another two-hour-plus download, so I reinstalled it from my Snow Leopard installation disc using Pacifist naively assuming Software Update would bring me back up to date. Well, that didn't work, and now I have a copy of Quicktime X Player that won't run on Lion. I tried redownloading the Lion installation package and reinstalling the correct version of Quicktime X Player with Pacifist again, but Pacifist can't handle Lion's installation package (it crashes when you try to install or extract anything). Well, I don't have a backup, so that's not an option, and I don't have any external devices large enough to back up my files and applications, so a clean install with Lion Recovery isn't an attractive option either. Is there any way I can install Quicktime X Player on my computer again without wipping my hard drive? Is it safe to let the original Lion intallation process I downloaded from the app store run again? Will it simply replace the relevant existing files no-harm-no-foul, or will I just further muck things up?

Yeah, I don't feel like taking any more risks. Obviously, I don't know what I'm doing.
On the support.apple.com article on Lion Recovery, it says "These steps will erase and reformat the storage device. This article will instruct you on setting up the storage device to use the GUID partition scheme and the Mac OS Extended (Journaled) format, which are required to install Lion and an Internet Restore partition on your external storage device. You should back up any important files that are on the device to a different drive."
I understand the necessity of a backup option, but I need to replace a failed superdrive, and that gets budget priority over reinstalling Quicktime. (My MacBook Pro, bought in Japan, shipped with a defective superdrive that could read but not burn - it could never burn and was just plain broken. I wasn't willing to part from my laptop long enough to get it replaced while it was still under warranty, let alone deal with Japanese Apple support, but now I have something that I need to burn by the end of the week.)

How do I reinstall QuickTime X for Lion on MacBook Air

I accidentally moved QuickTime X to Trash and then emptied the Trash. I'm now faced with most files gone and some still present in Trash because their properties are set to not allow it to be empited from Trash. I tried going through and setting the properties to allow the files to be removed but to no success. Can anyone help me remove the files left behind and reinstall QuickTime X.
PS...this is my first Apple computer. Thanks.

If you don't have access to another Mac so that you can copy the QuickTime Player application, you'll need to reinstall Mac OS X.
As to the Trash problem, try restarting the Mac and emptying the Trash again.
Regards.

Help! I need to reinstall quicktime-

I ran into trouble after I downloaded Perian and Divx, hoping to view and (eventually) save avi files from my rca small wonder camera as quicktime files. At first it worked, but very quickly quicktime began to crash when I would try to open one of these files - and the next day it began to crash whenever I tried to open any files at all. These included standard .mov files. So I got desperate and thought I'd better get rid of Perian and Divx for mac, which I did. Quicktime still crashed. So then, just now, I decided to uninstall and then reinstall Quicktime. I did what I had done with Perian - searched for "quicktime" and trashed everything I found. This was a mistake! because, when I downloaded Quicktime 7.5 from the Apple site, it's just an updater, and there is nothing to update. How do I get the full program back?!!

Thanks! It is working now.
BTW, what are people doing about mov files opening extremely slowly, dropping frames, and so on? That's why I installed Perian in the first place (and also to view avi files). But I don't want to mess up Quicktime again - so how can I fix these problems. Apologies for spamming my own thread - and thanks for the advice.

Need to reinstall QuickTime X - no disk

I have a MacBook that was came with Leopard but now has Snow Leopard; it received a new HD through AppleCare, and was given 10.6.3 during the repair. I was NOT given new install disks.
I now need to reinstall QuickTime X, which I (foolishly) deleted in a failed attempt to install QT 7 (to play AVI movies).
Downloaded QuickTime 7 will not install because my system says I have QT X installed.
How do I re-install QuickTime X (or install 7) to 10.6.3 without any Snow Leopard install disks?
Thanks.

Until you get a Snow Leopard disk, you won't be able to find the files anywhere.
For your original problem, Quicktime 7 should have been installed in the Utilities folder. You can't install the QT7 from a download because it is not the correct version to run on Snow Leopard. If you had a QT7 Pro license, it will work with the version of QT7 that should have been installed.

ReInstall Quicktime

SERIOUS PROBLEM! I need to reinstall quicktime after deleting the .app

I am trying to reinstall quicktime that came with my macbook pro, after deleting the quicktime.app file and the folders in the library.
You might ask why I did this? I have quicktime pro to install, but it's version 7.1.1, and would NOT install over 7.1.2; I messed up though, I know that now.
How do I fix it? Trying to reinstall quicktime 7.1.2 that I downloaded just crashes the installer.
Thanks!

No, I have not deleted the Quicktime712.pkg from Library/Receipts. Should I do this, or put the OSX disk back in the drive and then run the package that is in my Receipts folder?
I run software update religiously, so I know that is not an issue.
Thanks for the info, hopefully what I told you helps narrow the problem a bit.

Do I need to reinstall QuickTime?

Posted this in the QuickTime forum but aside from a spammer I've not heard from anyone. Hoping someone here can help me.
I'm new to Macs so I'm not sure how to proceed with a problem I'm having. I was trimming a couple of files in QuickTime and everything was working great until I tried to trim a larger file. When I tried to save it a popup window opened with a message saying "QuickTime application quit unexpectedly". Hitting the details button revealed a huge report (part of that report is pasted below). Since that error occurred, I can't trim and save any of my files. Every time I do I receive the same error message. I've restarted my Mac and have the same results.
Do I need to remove and reinstall QuickTime? Version is 10.4 (833). What can I do to troubleshoot and fix this problem?
Thanks,
Mike

is there any other to download my video recordings to my desk top?

HT3678 How to get Quicktime without a Snow Leopard Install Disc?

I purchased Snow Leopard through apple as a download. So I never received a disk. And I deleted Quicktime because it would not play audio. I thought I could just fresh reinstall it and it might fix the problem. Where can I download it without the disc? I have scoured the forums, changed Text files to qtz (but since I do not have quicktime on my machine anymore I can't ask Apple to download it for me)... Any ideas? Thanks!

Worth checking which version you deleted (deleting QT is never a good idea as it is an integral part of the operating system).
Mac OS X 10.6 includes QuickTime versions 10.0 and 7.6.3. The QuickTime 7 player will only be present if a QuickTime Pro key was present at the time of installation, or if specified as part of a custom install, or individually downloaded:
http://support.apple.com/kb/dl923
Snow Leopard update 10.6.4 included an update to 7.6.6 (if installed). You can install it from the above link even though it says for 10.6.3. It's the same version of QuickTime Player 7.6.6.
(Only QuickTime Player 7.6.3 or 7.6.6 can be updated to "Pro".)
A Mac OS X v10.6, OS X Lion, and OS X Mountain Lion-compatible version of QuickTime Player 7 is available for use with older media or with AppleScript-based workflows. QuickTime Player 7 can be used to playback formats such as QTVR, interactive QuickTime Movies, and MIDI files. Also, it supports QuickTime 7 Pro registration codes for access to QuickTime Pro functionality.

How to reinstall Tiger?

I want to COMPLETELY clean my 10.4.7 Powerbook G4, 1.5 GHz PowerPC, 512 MB DDR SDRAM (since I was a new mac user and downloaded ALMOST EVERYTHING i could possibly find :eek: and did not clean properly).
I still have the CD that came with my laptop (it says Mac OS version 10.4, AHT version 2.5, Disc version 1.1, then some numbers--serial maybe?).
What I want to happen:
+ erase all preferences, caches, apps, EVERYTHING!!! (I will back up my apps, files, etc. in my ipod.) ---> will dragging the main icon be sufficient, say for a program like Photoshop? Or limewire? Or Adium, etc.? Will that do enough back up? Or if I do that, the program won't work anymore when I drag them back?
+ get my mac like it was when it came from the store but really, the "new" feeling :rolleyes:
I've read a full tutorial on how to upgrade from panther, but not how to REINSTALL. Will it be safe to just insert the disk, choose erase and install, then fire away??? :confused:
A detailed help will be appreciated. :confused:
BTW, I think I dont want to include classic when i reinstall---what to do?

Hi cannonball8,
1. insert the install DVD and reboot while holding
down the c-key
2. Once the installer has started select your
language.
3. Select "Disk Utility" from the menu
4. Select your hard disk in the sidebar and click the
tab "Partition"
5. Reformat the drive.
6. Quit Disk Utility and proceed with a normal
install.
7. After the restart Repair permissions!.
8. Download and apply the Mac OS X Update 10.4.7 Combo
PPC.
For even more detailed information read this article:
Using Restore discs with computers that ship
with Mac OS X 10.3.7 or later
Good luck!
If this answered your question please consider
granting some stars: Why
reward points?
Just to clarify, why do I need to partition and reformat?
Also, upon the fresh reinstallation, what apps will I have? Is it safe to assume that I will have the free Apple applications already installed (bundled with Tiger) like Safari, iTunes, iPhoto, quicktime (non-pro), ichat, mail, etc.? Even though I would still have to update them? Is this right?
