Itunes won't open because it says Quicktime was not found?

When I click to open Itunes, first this message pops up: The procdedure entry point QTCF_CFHTTPPMessageSetHeaderFieldValue couldn not be locate in the dynamic link library QTCF.dll.
Then i click OK and the same message pops up, and then another one pops up saying: Quick Time is not found. Quicktime is required to open Itunes. Please uninstall Itunes, then install it again.
Except I checked, and i DO have Quicktime. So I uninstalled Quicktime, and installed it again. I opened iTunes and ir won't work. So I uninstalled iTunes and then installed it again. Still doesn't work...

If you definitely have a working QuickTime but iTunes thinks that you7 do not, then this points to a particular type of error.
Do you have a computer that has been set up for a work network? You may find that iTunes works OK when the computer is connected to the network but doesn't at home when not connected.
There are other possibilities, but this is a common one.
If I have guessed right, the problem lies in the %path% environment variable. In order to look at its contents, could you do the following:
Type:
cmd
into your search box and click cmd under Programs.
The black cmd window will open.
Next copy&paste the following into the cmd window and press return:
echo %path% >documents\path.txt
This will place the contents of the %path% variable in a text file called Path in (My) Documents.
Could you copy&paste this text file into your next post so I can look at it.
(Use ctrl V to paste into the editor, right click doesn't work.)

ITunes won't load, it says Quicktime was not found. QuickTime is required to run iTunes.

iTunes won't load, it says Quicktime was not found. QuickTime is required to run iTunes. Please uninstall iTunes, then install iTunes again. I have done this several times and it keeps showing me that Quicktime is unavailable even though I redownload it every single time.

Uninstalling iTunes and reinstalling should not affect your library. You should backup anyway.

HT1926 My itunes won't open because it says "This application has failed to start because MSVCR80.dll was not found. Re-installing the application may fix this problem" Can someone help? I don't want to delete it altogether due to needing the phone backup

I was given notification to upload the latest version of itunes recently, so I clicked installed. However it has since corrupted my itunes and I get the error message:
"This application has failed to start because MSVCR80.dll was not found. Re-installing the application may fix this problem".
In poor timing, I have also accidently damaged my phone and have a new one to restore it to an old back up.
It is because of this I am reluctant to completely delete itunes off my computer and start again for fear of losing my back ups.
Is there another way to fix iTunes so I can open it again?
Thanks

Hey I finally got an older vesion of itunes to work!!! 10.7 x64 for windows 7
After uninstalling all apple products even quicktime
I had to delete everything from (program files, and program files x64, program data,)
And all downloads from apple, and I went in to search deleted other stuff from apple, and itunes
But definently not my itunes library and Playlist
Down loaded 10.7 x64 for windows 7, but checked (do not start when done)
Then I emptied my recycling bin and restarted my PC
I ran geek tech tool box same as reg cure pro, also PC Tools registry cleaner, and CC Cleaner
Then I emptied my recycling bin and restarted my PC
And wallah... It finally works, and I Love the older version anyways.
Easier to download and transfer music!!!!!

ITunes won't open, because it "needs QuickTime 7.0.3"--but I have it!

Same sob story, to a degree, that I've been reading about. BUT--when I click on the iTunes icon, it says it can't launch because QuickTime isn't up-to-date. That isn't accurate, because they download together! This is on a brand new computer, Dell Inspiron 6000. I have uninstalled the download and tried the CD that came with the Nano (an older version), and it installs but won't run, either. Just wants to send an error report to Microsoft each time I try to open iTunes.
I've tried a lot, including choosing iTunes not be the primary audio player. QuickTime doesn't successfully install when I tried a separate installation.
Running XP small business edition (just a souped-up version of Home edition). Computer also runs Microsoft Media Center...could this be part of the problem? I'm also running McAfee Security Suite.
Anyone have any ideas on how to get this going?

Well, then we need to get rid of every Quicktime reference on your computer and start anew.
to Verify That All QUICKTIME Files Are Removed
Go to: Start/Find/Files or Folders.
Enter QuickTime as one word in the Name box.
Click Find Now (be sure you are in the C drive of your computer).
Confirm that the following files are NOT on your computer. If they are still on your computer, delete them.
QuickTimeInstaller.ini
QuickTimeInstaller.exe
QuickTimeInstallCache.qdat
then reboot your computer
OR
Close the program tray icon (lower right corner of taskbar) before trying to remove (or installing standalone)? ( or ctrl alt del and close these first: iTunesHelper.exe, qttask.exe)
or:
Start - Run - copy and paste this into the run box:
C:\WINDOWS\unvise32qt.exe C:\WINDOWS\System32\QuickTime\Uninstall.log
(check to see if there is a file "uninstall.log" in the C:\WINDOWS\System32\QuickTime folder)
last resort (since you cant get rid of it anyway) -
delete c:\program files\quicktime folder and c:\windows\system32\quicktime folder
run regedit - delete these keys:
HKEYLOCALMACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Quic kTime
HKEYLOCALMACHINE\SOFTWARE\Apple Computer, Inc.\QuickTime
Then, try downloading Quicktime Standalone and see if iTunes will open up after that. Good luck and keep me posted either way.

Microsoft Excel won't open because it says there is not enough memory?

I'm trying to open Microsoft Excel and a prompt appears stating that there is not enough memory even though I have 140gb available of a 250gb hard drive. Any suggestions?

You're right, i did. But how do I clear out available RAM? When I check the Activity Monitor and then System Memory it says I have 1.3gb available. That SHOULD be enough. Right?

Firefox 4 won't open because it says it is not supported by the current architecture. Now I cannot use Firefox at all.

I followed the advice and instructions to download Firefox 4 and once I moved it to the applications folder, a slash went through the icon and now it tells me that I cannot open Firefox because it is not supported by the architecture. Don't know what to do next.

I suspect you need more expert help but here are a few things you can try.
If you can't open Firefox(double click on Firefox desktop icon) try Safe Mode - Hold down the Shift Key as you double click on the icon>don't check anything on the page that opens>continue. If Firefox opens and works in this safe mode go to Add-ons> Extensions and look for "Ask". Then look at Add-ons >Plug-ins and again look for "Ask" . Remove, delete,disable any Asks. If you do remove any, close Firefox. And try again in Normal Mode.
The Ask website has detailed instructions for removal but you need to find it on your computer and have your computer in working order.
If there is no sign of Ask and Firefox is working well in Safe Mode you should work your way through this -
https://support.mozilla.com/en-US/kb/Troubleshooting%20extensions%20and%20themes
Eventually you might need to grapple with About:Config and even your Windows Registry but I would recommend a complete uninstall and re-install before that. Unfortunately that often doesn't work.
That all sounds very daunting but taken step-by-step you might get lucky early.

HT201413 updated last night and now ipod says to coonect to itunes which i cant because apple application support was not found. tells me to uninstall and reinstall itunes. Will i lose all my music or is it still on my ipod?

Updated ipod last night and now when turned on tells me to coonect to itunes (picture of usb cable with arrow to itunes). I can't connect to itunes on computer because apple application support can't be found. Tells me to uninstall then reinstall itunes. Will I lose all my music or is it still on my ipod?

Under normal circumstances, an uninstall/reinstall doesn't touch your content. (That being said, it's still always a good idea to maintain a current backup at all times in case of disasters.)

Firefox won't open because it says it is already open when it ain't

Firefox won't open because it says it is already open. It appears Firefox is operating in the background. Tried to remove it but we get the same message to log out of Firefox. For 10 years we have been using McAfee with all features but it does not detect any virus or malaware etc. It appears it might be a malaware problem but even using all the latest Microsoft fixes hasn't helped. We used Vista Business Professional with all the latest service packs updated. We use the latest version of Firefox as of up to around 3 weeks or so ago when this issue first appeared.

I have the same problem. I'm using Mavericks OS and latest iMovie. Both downloaded last week. I save the movie into File (as directed) and QuickTime

If you haven't deliberately tried to downgrade iTunes then it is possible the library is corrupt. This approach should work.
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!

I ran an itunes update, but now itunes won't open as it says it hasn't been installed correctly. How do I reinstall it?

I ran an itunes update, but now itunes won't open as it says it hasn't been installed correctly. How do I reinstall it?

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.
