ITunes won't open, QuickTime error message

By accident, I deleted QuickTime, and can now not open iTunes, so I downloaded QuickTime again, recieved a message that QuickTime has been successfully downloaded, but when I try to open/run it, I get this error message:
"C:\Documents and Settings\Owner\Local Settings\Temporary Internet Files\ContentIE5\TYMNQEZC\Quicktimeinstaller[1].exe is not a valid Win32 application"
I am a computer illiterate, Please help me!

hmmm. let's try an alternate technique for swapping out your QuickTime that doesn't involve redownloading an installer.
first let's just make sure your previous QuickTime is thoroughly gone.
head into your Add/Remove programs. uninstall QuickTime.
Next, we’ll manually remove any leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
5. Navigate to C:\Windows\system32\.
6. Remove the files QuickTime.qts and QuicktimeVR.qtx.
7. Restart your computer.
next, we'll get a fresh copy of QuickTime into your PC by doing a repair install of itunes.
switch off antivirus and antispyware applications prior to the repair install.
go into Add/Remove and select itunes. click "Change" and then click "Repair".
if the repair install goes through okay, restart the PC and try launching itunes again. does it launch properly now?

ITunes won't open - wordless error message

When I try to open itunes, I get a wordless error message that only shows a red octagon behind the itunes application symbol. The only option is to click 'OK'. Any ideas what this is and how to deal with it? I haven't used itunes in a few weeks, so I have no idea when this problem occurred. I've searched online and in the forum, so apologies if I'm missing something obvious!

Try removing the Genius database. In the "Finder" go to the /username/Music/iTunes/ directory and delete the "iTunes Library Genius.itdb" file. This may allow the program to launch again. This file will be recreated upon first use of the "Genius" feature.

ITunes Won't Open - QuickTime Error?

Hi there,
I ran a system restore on my computer because it was acting a little weird, and when I went to open iTunes, it wouldn't open. I uninstalled, reinstalled, restarted my computer, shut off my computer.. everything.
I keep getting the following error message:
"QuickTime was not found.
Quicktime is required to run iTunes. Please reinstall iTunes."
I've tried this, about 5 or 6 times to no avail.
Any help would be greatly appreciated!!

Things seem to have got in a muddle, it is probably best to remove all iTunes related programs and start gain. I will give you a method for removal and phased reinstall of Quicktime. I have included installer cleanup, but this is only required for any programs wher the uninstall fails.
If you computer was acting funny, have you checked for malware? That can cause problems for iTunes.
Download a fresh copy of iTunes and the stand alone version of Quicktime (the one without iTunes)
http://www.apple.com/quicktime/download/win.html
http://www.apple.com/itunes/download/
Download and install Microsoft Installer cleanup utility, there are instructions on the page as well as the download. Note that what you download is the installer not the program – you have to run it to install the program.
To run the program – All Programs>>Windows Install Cleanup
http://support.microsoft.com/kb/290301/
Now use the following method to remove iTunes and its components:
XP
http://support.apple.com/kb/HT1925
Vista
http://support.apple.com/kb/HT1923
*If you hit a problem with one of the uninstalls don't worry*, carry on with the deleting of files and folders as directed in the method.
When you get to deleting Quicktime files in the system32 folder as advised in the method, you can delete any file or folder with Quicktime in the name.
Restart your PC.
Run the Microsoft Installer Cleanup Utility. (Start > All Programs > Windows Install Clean Up)
Remove any references you find to the programs you removed - strictly speaking you only need to worry about those programs where the uninstall failed.
If you don’t see an entry for one of the programs that did not uninstall, look out for blank entries or numeric entries that look like version numbers e.g. 7.x for Quicktime or 1.x for Bonjour.
restart your PC
Install the stand alone Quicktime and check that it works.
If it does, install iTunes.

Itunes won't install. Error message: Apple Application Support not found

Itunes won't install. Error message: Apple Application Support not found. What is the fix for this?

It is always these four updates that fail. I've tried downloading and installing them seperately from apple downloads. I've tried various recommended fixes, and nothing I can figure out works. Before these problems, itunes worked on the computer for a year.
Thank you again for wanting to help me.

Itunes won't open- unknown error -50

My itunes won't open. everytime i click on it, it says unknown error -50. I have read other post and ppl say deauthorize it and authorize it again. But how am i suppose to deauthorize it when I can't even see the screen or it wont open at all. Please help me fix this. any help would be greatly appreciated. Thank you.

Did you get any resolution yet??? I have the same issue. Have uninstalled\reinstalled a million times. Have done system restores back as far as possible. NOTHING works!!!!!!! UGGH!!!

Itunes 7 won't open, no error message, also another new strange problem

I found a thread for this awhile ago and followed it and it worked. However, I can't find the thread again, and after I restarted my computer, itunes once again would not open. I'm not getting any error message, just a brief moment with the hourglass symbol up and then nothing. So far I have uninstalled all itunes/quicktime products from my computer and reinstalled a few times, but nothing seems to work. Any help would be greatly appreciated.

some preliminary questions aimed at narrowing in on possible culprits.
(1) do you have Norton Internet Security 2005 installed on the PC?
(2) try launching your QuickTime. does it:
(a) launch perfectly fine?
(b) fail to launch with an error message? (if so, what does it say?)
(c) exhibit other peculiar behavior? (if so, could you describe it for us?)
(3) reboot the PC. bring up your Task Manager, and click on the "Processes" tab. now try to launch itunes again.
does an "itunes.exe" process appear in the Processes tab? if so, does it persist in there or does it disappear after a few seconds?

ITunes Setup downloads iTunes 7, but iTunes 7 won't open, no error message

So I've been at this for months, trying to update my iTunes from 6 to 7, and previous versions have opened on my laptop, but this time, NO! I've downloaded the setup for 7, it loads the program and we restart the computer so that it can get the new parameters straight, so then I try to open iTunes and the mouse pointer gives me the hourglass and the iTunes icon flickers and turns to a white box for a split second and back to the regular icon. The program doesn't open, I don't see an error message, nothing. I got an Ipod nano for Christmas and I can't use it because it needs iTunes 7! Has anyone had this problem? I've read so many threads and topics here but I haven't seen any answers to this one!
I've tried reinstalling it and deleting it and reinstalling it. I've also just tried updating using the Apple Software Updater (instead of downloading from the Apple website) and it gives me an error. Hmmm... I guess I should figure out what that error says too. But anyway, I need help!

So I've realized that iTunes needs service pack 2 for
XP, and I have 1, so I'm trying to download it, but
that's not working either... I wonder if you know
windows as well as apple? I have to turn the Active
x controls on and this tool bar is to appear so I can
do that but I can't get it to appear. I've tried
raising the security settings but nothing appears...
interesting.................what is service pack 2 and where can i find it? My itunes still flickers on and off when i attempt to use it. .. and how do i get to the active X controls so that i can adjust them? Thank you guys so much for your time and assistance :-D

FINALLY got my iTunes to update but now it won't open, the error message is "iTunes Library.itl" cannot be read b/c it was created by a newer version of iTunes.

This is getting irritating. I finally get the update to install now I get this new error message, I don't get it. I have Windows 7, all the updates have been installed on that, but I can't get the stupid iTunes to open. Seriously annoying! Can anyone help me?

I don't know why this error occurs, unless you have attempted to downgrade iTunes.
This method should get you up and running again.
Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

ITunes will not open (no error message and not running Norton 2005)

I have recently upgraded to iTunes 7 and I now cannot get it to open after clicking on the icon. The iTunes.exe process comes up in the task manager briefly then disappears. There is NO accompanying error message and I am NOT running Norton Antivirus 2005. I have already tried reinstalling the standalone version of quicktime and I have used msconfig so that I essentially have only the necessary iTunes/quicktime processes running (no antivirus/antispyware/anti-popup software is running in the background). I have Windows 2000 and I have never had a problem with iTunes until now. Somebody please help me out here.

wapierce,
It looks like we have covered all the bases here. Unfortunatly it looks like The computer cannot run iTunes or the OS has an issue that may require a reeinstall.
Lets verify the Hardware and OS one more time. Click Start> right click My Computer> Properties(you can also open My Computer then click view system information on the left side of the window.) What does the processor and Memory say here? Also what is it saying aout Windows.
Make sure there are no upadtes available for the computer.
When you installed iTunes did you make any registry changes? It sounds like the next step would be doing a restore or re-install of Windows on the computer.

Itunes won't open. says error report

everytime i click on itunes a window comes up saying
"iTunes has encountered a problem and needs to close.
we are sorry for the inconvenience."
then at the buttom there are two links sayind SEND ERROR REPORT and DON'T SEND.
clicking either one won't do anything.
neither will uninstalling it and reinstalling it.
or restarting my computer.
i need help.

let's first check to see if this is associated with a problem with your QuickTime. (iTunes needs a properly functioning QuickTime in order to work correctly.)
try launching your QuickTime. does it:
(a) launch perfectly fine?
(b) fail to launch with an error message? (if so, what does it say?)
(c) exhibit other peculiar behavior? (if so, could you describe it for us?)

ITunes won't open! Error -42404

I was recently upgrading my computer with upgrades that my mac came up with for me and my computer shut down in the middle of it. When I turned it back on again the upgrade window was gone and when I tried to open my iTunes I got this error message: "The iTunes application could not be opened. A required iTunes component is not installed. (-42404)."
I've searched for this error on the support pages and have found nothing. Help?!

I had the same error messages. Quick and easy steps:
1. Control panel/ remove All quick tunes and itunes.
(if itunes will not delete another step involved)
2. itunes did not delete, you must install window installer cleanup.
search down the file for itunes highlight and remove. Do the same for quick tunes if still present.
3. Start/search for files and folders: "itunes" delete them all, "Quicktime" delete them all.
4. Your choice, go to itunes and down load Quicktime & itunes together, or go to google and download seperately. (my choice to do seperately).
5. NOTE: ( don't know if this was necessary) but rebooted computer after each step.
Through much trial and effort and a bunch of research, it finally worked.
GOOD LUCK to all. Hope this works well for you all.
