Quicktime Pro 7 refuses to launch independently after installation of AVID MC7 / Sorenson Squeeze

Hi guys,
Hopefully someone knows a fix for this.
After installation MC7 and Squeeze, i can no longer launch QT / QT Pro. The only way i can play .mov files is via iTunes, which for me is less than desireable. So the codec is obviously there.
Please note that QT 7 (non pro) was working fine prior to installing Avid & Sorenson.
I've tried 'repairing' QT by downloading the file, but even after the repair it still refuses to launch.
Also, QT is non longer listed in the 'open with' options... Please help!
Windows 7 home x64 (latest ver.)
x6 Phenom 945
8GB Ram
GTX 560 ti

Good catch!
I must note that when i launch QT from the start button and it prompts the user account control popup, i notice the target is in 'Program Files - Quicktime Alternative.'
It'll probably be a conflict with QuickTime Alternative (It's a third-party chop-down of QuickTime) and the standard QuickTime Player.
Head into your uninstall a program control panel. Uninstall QuickTime, then uninstall QuickTime Alternative. Now try reinstalling the QuickTime Player:

Does the player launch for you now?

  • Leopard 10.5.7 refuses to launch applications after "erase and install"

    I have an older iMac G5 (1.6Mhz PPC, 2 Gb RAM) born with Panther OS. I wanted to update some applications so I could have a secure browser and other apps. I upgraded the RAM to 2 Gb as a first step. The additional RAM really perked up the old iMac so the next step was to update the OS to 10.5.6 using a DVD that was printed in Jan '09 and sold as part of a bundle pack with the new iLife 09 and iWork 09.
    I thought I could get away with an overwrite installation and I knew there were risks in doing that. The result was a really bugey computer with frequent terminal views, kernel panics and even hard shut downs. Apple issued the 10.5.7 update and that helped stabilize the system somewhat.
    I still had problems with instablility of the OS and with Safari 3.2.3, Firefox 3 and other applications. I decided to reinstall Leopard using the archive and install procedure. The 2nd install stabilized the OS but I still had problems with browsers and Open Office refusing to launch.
    I did lots of troubleshooting using Onyx, MemTest OSX, repair permissions in the Disk Utility, etc. I created a new user account and the problems persisted. I decided to try a third install of the OS using the Erase and Install procedure.
    The system now has Safari 4.0.1 but after a few page views Safari crashed and now it crashes as soon as you launch it. A freshly downloaded Camino browser does the same thing. iTunes, System Profiler and a fresh download of Onyx also refuse to launch. All of them crash while launching.
    I can launch an ancient version of IE and Firefox 3 from the desktop.
    After the last OS X install, I noticed the system did not accept the first attempts at downloading the Leopard updates and the Safari update. A second attempt was successful for both. I am reluctanct to proceed with installing anymore applications until I can fix what I believe is a problem with the OS. The OS worked well after the archive and install procedure and I am thinking it should be able to work at least as well after the erase and install.
    I live in a rural area and the nearest Apple "genius" counter is about a 5 hour round trip. Is there anyone out there that has encountered this problem?

    The Internet Explorer came with the iMac and I never used it. I had it on a disk so I put it on the desktop to get a download of Camino after Safari failed. It's so old that most websites can't render for it unless they have some html default page.
    Here is what the Crash Reporter log had. The iTunes was on the OS X install disk. The Camino browser was downloaded from Caminobrowser.org.

  • Premiere Pro CS4 crashes on startup after installation (Win XP x64)

    Hello,
    I've had no such luck getting PP working on Win XP x64, I've installed everything else and checked to make sure its working correctly from the master collection, but PP is giving me a hard time.  After reading much of the other discussion on this problem, I have yet to find a solution that works for me, things I've tried thus far:
    - Re-installing
    - Re-installed fonts etc.
    - Switched user accounts
    - Removed Quicktime
    None of these have worked, Adobe's error reporting tool is garbage I cant even read the crash report data, so I'm stuck......anyone have any good ideas throw them up here, otherwise its time to get angry with tech support....

    Sorry to bump a dead thread, but I fixed OP's problem on my computer after doing pretty much all he had done. I signed up for anyone else that might be looking for a solution to this problem.
    Browse to "C:\Program Files (x86)\Adobe\Adobe Premiere Pro CS4"
    Find "Adobe Premiere Pro.exe" and right click it and click on "Properties".
    Go to the "Compatability" tab and check "Run this program in compatability mode for:" and select "Windows XP" in the drop down list. If you arent on an administrative acount, you may have to switch to it and select "Allow non-admins to run this prog". I tried this after reinstalling, changing the path, removing any registry entry I could find with "premiere" in it, and even trying to use a pirated version. Before you go pointing fingers about that, I get the entire adobe production and design suite for free thanks to my school, IUPUI (http://uitsnews.iu.edu/2008/12/10/new-agreement-makes-adobe-software-available-on-iuware/)  and I needed it for an assignment. Protip, adobe: The pirated version actually launched correctly once, but after a system restart, crashed on start up like before. Just something to think about.
    Heres a launch shot + system specs for a refrence:

  • QuickTime Pro for Windows cuts off after about a second?

    Pro version of QuictTime worked fine at first on Vista 32bit. (Don't judge me becasue I'm using Vista, please!) Used it for video editing last fall. Now I find any video or audio file I try to play cuts off at about 1 minute. Only way to get it to play an entire movie is to turn on "Play All Frames" or else mess with playback speed -- and in both cases audio gets turned off. I have tried resetting just about every preference and view setting I can find. Uninstalled and reinstalled. Was especially careful to make sure I did not have playbe restricted by means of "Play Selection Only." Furthermore, teh start-stop bracketting controls have no effect.
    This happens with all kind of video and audio tracks.
    I am at a total loss. Searched Windows Registry for something amiss but found nothing. Even being a software developer myself I just don't see what is amiss. Could this be due to some nasty codec? Conflict with other software? Only new media software on this machine I know of is Adobe's and I never even use that.
    Help?

    I haven't [yet] tried it with other M4V files, but I will and get back to you.
    BTW, after it crashed, I restarted QuickTime and opened the newly-created "self contained" movie and it seemed to play OK,  So despite the inconvenience of having to restart, the crash didn't seem to affect the end product of my work.

  • Acrobat XI Pro not listed under applications after installation

    Mac OS: 10.9.1
    Processor: Intel Core i7 2.3GHz
    After installed Acrobat XI Pro, it is displayed in the Creative Cloud Desktop as "Up to date"
    But not listed under "Applications" folder.
    Could not find Acrobat XI Pro anywhere in the computer.
    When you choose "Open with" option for pdf file, not displays Acrobat XI Pro.
    Instead it displays the older version Acrobat Pro 9.
    Someone please help to fix this.

    So, I completed all the steps with no luck. Uninstalled CC and all its components, ran the cleaner, etc. When I reinstalled a fresh version of the Creative Cloud Desktop App, it showed as if Acrobat XI Pro is already installed - see attached screen shot. Any other suggestions?

  • My Poster Frame I set in QuickTime Pro doesn't stay set after export.

    I drag my fcp cut into QT Pro. I set the Poster Frame. I choose 'Go to poster frame' to make sure it's set. Then I export it for ipod and open it in itunes and the poster frame is wrong. This has happened twice. Any ideas? Thanks.

    Any "Edit" or "Export" will remove many of the features found in the source file.

  • How do I hide Quicktime Pro registration code?

    I have several Windows terminals in my workplace waiting room which I provide for customers to access multimedia content. I want to have Quicktime Pro on these machines, but after I enter in my Quicktime Pro serial number, there is nothing stopping somebody from clicking Edit > Preferences > Register, and then doing a Copy & Paste of my registration code and emailing to themselves!
    Is there anyway to hide my registration code?  Why do Apple even bother making users pay for this software, when they make it so easy to compromise?

  • Quicktime Pro - Windows 8 - installs, but refuses to run!?

    I've uninstalled and re-installed Quicktime (and iTunes) several times already.  I've run CCleaner to clean up any remaining pieces and re-installed afterwords.  Nothing is solving my problem.
    Quicktime (Pro) installs fine on my system.  However, when I run it, nothing happens.  If I check the task manager, I see Quicktime.exe using 0% CPU. 
    If I double click on a .mov file, the same thing happens.
    This is a system I use for my work and I deal with MOV files every day of the week, so this is a big problem.
    Does anyone have an idea what could be done to fix it?
    Thanks,
    Paul

    Disable any internet security temporarily and then give it a try, that could be stopping QT from opening? If not try opening QT by going to C:\Program Files\QuickTime and double click on QuickTimePlayer exe. I'm assuming you're trying to open from a desktop shortcut icon, that may be corrupted?

    But now, one day later, when he starts computer, it refuses to lauch when iTUnes is clicked. just acts as if nothing was happening.
    So tried to uninstall iTUness and planned to do a reinstall, but now the uninstall has been running 30 minutes and seems to be doing nothing.
    Any thoughts on what is going on here?
    Should I force the uninstall by using a 3rd party Uninstaller tool?
    Should I download iTunes + Quicktime separately as EXE and run the installer again (I have downloaded it (57MB) to my Mac and plan to take it over to the Vista laptop on Monday when i am there again).
    Any other thoughts on why it worked once after the install and now has gone silent?
    thanks!

    Well that's weird that it quit working. Was that the first time the PC had been restarted since a lot of stuff got installed?
    The uninstall shouldn't take more than a min or so.
    Use the Microsoft Installer Cleanup Tool:

    Norton or other security software can cause that, there are several other reasons too...

  • After buying Quicktime Pro, I can't get it to run

    I just bought Quicktime Pro, and I can't get it to open. Even after restarting my computer, the Quicktime Player opens fine, but not Pro. (I put my key # in the Quicktime control panel, and it registered "Quicktime Pro"... just like the instructions.

    Just to make sure you're clear, QuickTime Pro is not a separate application, so nothing different will launch. A Pro key just unlocks the extra features of QuickTime Player and the QuickTime browser plugin. If the Pro labels have gone from the menu items in QT Player, then your key is correctly registered and you should be good to go.
