Quicktime Desktop Icon won't open

I click on the QT icon on my desktop and it won't open the program, but if I click on a QT file, the program opens with no problem.
I just uninstalled QT and then reinstalled it, and I keep getting the same problem. Any help on this? Thanks.

Does the program open if you go "Start > All Programs > QuickTime > QuickTime Player"?
(Trying to get a feel for the full scope of the problem.)

I wanted to try out photoshop before I bought it, so downloaded the trial of the creative cloud and whilst was downloading photoshop, it crashed my laptop, forcing me to restart it and now when I try to open the creative cloud icon on my desktop it doesn't open at all. Can anyone suggest anything please?

uninstall it using the uninstaller, clean per Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
and then try reinstalling.

My desktop icons won't open but I can open them from the finder thru the dock; how can I fix this? I run 10.5.1

I run 10.5.1 and I have been getting a blue screen on boot that takes forever before the screen icons pop up...then I can't open them by clicking on them even though I can do so thru the finder in the dock. Any ideas how to fix? I dumped a bunch of stuff my boot drive to free up space...I have aropund 130 out of 160 gig that's available.

Go to your Applications folder where you have installed these applications that will not open. Right-click, or two-finger tap (if enabled) the application icon. Choose open, and the application will launch. This is a one-time deal, as afterwards, that specific application will launch normally.
This is an Apple security mechanism. You can override this in System Preferences > General: Allow apps downloaded from: Anywhere. However, it is not set to Anywhere to protect you, and even I do not leave Anywhere permanently enabled. Only for those apps that I know are not in the App Store, and already know have this open behavior.

Numerous websites linked to desktop icons won't open with Firefox as my default browser, but will when I subsequently designate Internet Explorer as the default browser. However, when I select IE, I cannot open Firefox. How do I fix this? CharlieA

When I designate Firefox as my default browser, I cannot open any destop link to any website, except Mozilla. When I change that designation to Internet Explorer, I can open all destop linked websites, except for Firefox. What do I do?

Sometimes Windows gives you weird error messages when you click a link in another program or double-click a desktop shortcut. These messages usually occur only when Firefox was closed and has to be launched before the link can be loaded. Is that what you're getting? This occurs when Firefox's registry settings get crossed up, as described in this article: [http://kb.mozillazine.org/Windows_error_opening_Internet_shortcut_or_local_HTML_file_-_Firefox Windows error opening Internet shortcut or local HTML file - Firefox - MozillaZine Knowledge Base].
If that isn't it, what happens exactly?

Hard Drive icon won't open and menu bar flashes off and on

All of a sudden, in the middle of the day, my eMac went haywire. I can launch apps and docs are one the desktop. But I cannot open the Hard Drive icon. If I double-click on it (or used Command-O from keyboard), the icon won't open. And when I attempt to open it, the Finder Menu Bar begins flashing off and on (vanishing, reappearing, vanishing) across the top of the screen. I haver rebooted, run disk utility to repair permissions, even booted from TechTools to run its diagnostics. But still no access to the Hard Drive icon. I logged out and logged in as a TEST user, and same thing happens even when logged in that way. Literally, this happened in an instant. One minute the eMac was fine, then this started. Anyone else seen this? -- david

If the problem exists in both your regular account and your Test account odds are that it is at the system level. You can try a Safe boot (hold down the shift key at startup) to see if there is a third party startup item or one of the optional Apple functions that is causing the problem. You could also boot from the installer disk and use the Disk Utility->Repair Disk function. If you have a utility such as Tiger Cache Cleaner which will do a deep cache clean you can also try that.

After downloading iphone pictures to desktop, itunes won't open. I downloaded itunes 10.6 (64bit) but get "Do you want the following program to make changes to your computer?" Apple Inc. I've clicked "yes", restarted the computer, and still no luck.

I also have the same problem, but the Software Updates tool doesn't recognise that Quicktime is out of date. Have you tried downloading Quicktime 7.7 Leopard from http://support.apple.com/downloads/#quicktime as this worked for me...?

Help! Icons won't open

I have a problem recurring on and off where when I turn my computer on, none of the icons open. I have to manually shut it down with the button, Then, when I start up again there is often just a black screen, or the same thing happens where the icons won't open, or it starts a disc scan. So far, if I walk away and come back to it much later in the day, it will work again. Am wasting so much time, and I am am afraid one of these days it just won't be usable at all. I have a toshia satellite, just barely a year old, with windows 7 (which I loathe.)( Any suggestions? I have tried the geek squad and gotten nowhere.

Go to START/MSCONFIG and disable all startup programs (under the STARTUP tab) except your anti-virus. This is a possible error occuring from a memory leak in a background program, so this might assist. Please post results or any action you've taken in testing/resolving.

Why Facebook app icon won't open?

Why Facebook app icon won't open? Just gives me a blank page

I believe that i've had this problem before, either restart your iMac, or un-download the app and remove the app icon from your dashboard and then re-download it.

Hard Drive icon missing - Desktop folders won't open - Need Help!

I need help! I have a 400 MHz PowerPC G4 with 768 MB SDRAM, no DVD drive - was running OS X 10.3.9 quite happily. We became owners of a new iPod Nano - so we had to upgrade to 10.4.
(I'm writing this on my 800 MHz PowerPC G4 with 768 MB SDRAM, (also no DVD drive) that I upgraded from OS X 10.3.9 to 10.4.11 without incident.)
Installed 10.4 using a FireWire Hard Drive - installed software updates to 10.4.11 - ran Disk Utility - ran MacJanitor - ran DoktorKleaner - everything was working well.
Rebooted and the Hard Drive Icon had disappeared from desktop. Folders on desktop have all lumped together in the top right hand corner of the screen, and refuse to open.
Only programs in the dock still work - clicking on the Finder icon only gives the option to hide. New Finder Window does not work. Programs can be found in Spotlight, but if they're not in the dock they won't open. Trash won't open or empty.
I attempted to reinstall Mac OS X using FireWire, but now the Hard Drive is full and is telling me it will erase and reinstall. I need to save files off this computer now (Sadly no backup exists) before my wife readies divorce papers.
I tried using FireWire Target Disk Mode to copy files - with the 400MHz as Target I just get a spinning Beach Ball any time I click on the Icon. After far too long it opened up an empty window.
With the 800MHz as the target, the 400MHz does not show it on the desktop, so I have no way of copying files to it.
Anyone have some advice that doesn't involve a time machine?

Whenever something starts going wrong with the computer I suggest you first boot from the installer disk, select language if applicable, choose utilities, run Disk Utility and verify (and repair if necessary) the drive. Then repair the permissions on your computer. You can also repair permissions from DU on your main drive while booted, but to properly verify and repair your drive you have to run it from a drive other than the boot drive.

[Disk Utility's Repair Disk Permissions|http://docs.info.apple.com/article.html?artnum=25751]
From BDaqua (couldn't have said it better):
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Then Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes."
A few questions:
Was this a retail installer disc that you used to do the upgrade?
How much free space do you have on the computer?
Did you use the [PPC Combo updater|http://www.apple.com/support/downloads/macosx10411comboupdateppc.html] to get to 10.4.11?
Did you do all these updates in one single session or restart and check your computer had accepted them okay between each update? It is critical to repair permissions before and after each update otherwise the installers won't install fully and you end up with a mix of versions.
You can set the Finder Preferences, general, to display a hard drive icon, but it sounds like your problems are going beyond that?
You can also try trashing your Users -> home folder -> Library -> Preferences -> com.apple.finder.plist file and see if that clears up the issue. That sets the Finder preferences and if it gets corrupted it will cause Finder problems.

Firefox will only open once from desktop and won't open new tabs or windows

When I clicked on Firefox's desktop icon this morning it took a solid 5 minutes for the browser window to open, and at that time I just chalked it up to my computer being slow.
Once it did open I soon encountered the first problem: when I clicked on "Open Link in New Window" or "Open Link in New Tab" nothing happened. Subsequently, when I did navigate to a website I was unable to click on any links whatsoever. I closed the window and tried to restart Firefox which is when I ran into the second problem: it wouldn't open. I opened the Task Manager and terminated firefox.exe, attempted to open via both the desktop icon and program folder but had no luck. If I restart my computer I'm able to open just the one browser window but with the same results of the first issue I mentioned.
I've tried all of Mozilla's troubleshooting tips in the "Firefox will not start" section with no luck. I've also uninstalled then reinstalled with no luck.

'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''one at a time''' until the problem reappears. '''You MUST close and restart Firefox after EACH change''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Desktop icons won't display on Desktop

I recently installed a couple of what seemed to be interesting menubar items (MenuStrip and Isolator). Shortly after (not concurrent with) I lost the icons that show up on the Desktop of files in the Desktop folder. The files are all intact - nothing lost, they just don't show up on the Desktop.
I've removed these two applications using AppZapper, run the new DiskWarrior 4.1.1, repaired the permissions, run repair disk from Disk Utility, reinstalled Leopard from the DVD, and now I'm at a loss on how to bring back those icons.
I'm running OS X 10.5.5 on an Intel Mac Mini. I use a Newer MiniStack as my boot drive. If I boot from the internal drive (which is virtually virgin from the day of purchase), the Desktop icons from that user are displayed as they should be.
Is there someway to "rebuild" the Desktop or otherwise bring things back to normal?
Thanks in advance,
-Tod

Added info:
I also recently tried using Path Finder 5. It also has been "shredded."
I was just poking around my Desktop and found that clicking on the Desktop itself while another app (say like Safari) is frontmost, clicking won't bring the Finder to the front. Sounds like something left over from Path Finder, though I deleted all its prefs using AppZapper.

QuickTime Player Document won't open

I tried opening it a few times and checked permissions, (I think they're set right) and QuickTime won't open my QuickTime Player Documents. The end part is .ml20.
Any advice?

"checked permissions, (I think they're set right) "
Do you actually mean you checked your QT MIME settings? Asking because you really don't check permissions to set anything.
Repairing permissions involes the following:
Save and/or quit your applications & doucuments
Go to Applications>Utilities Folder
Click Disk Utility
Click the Volumn (HD) that you want to check.
Click the Repair Disk Permissions button. (Don't worry about verifying)
At the bottom of window when the repairs have finished, you will see the “most important thing”:
Permission Repairs Complete
The previliges have been repaired or completed on the selected volumn.
Restart your computer.

Lost quicktime desktop icon

I updated i-tunes to 7.5.5 version. When computer was done updating my i-tunes icon disappeared and reappeared again as it always does with an update. My quicktime icon disappeared too but never reappeared. I had many problems with quicktime on my old computer. I am trying to keep it all clean and working on my new laptop. Is there a way to get my icon back? Is this a sign that my quicktime is going to begin having problems again? Someone please advise! My i-tunes seems to be working fine at the moment.

The Desktop icon is merely a shortcut and most modern installers have a simple check box to allow one be made (or not).
Don't worry about it or make one.
