Itunes.exe Entry Point Not Found - Error 7

Need help regarding error messages as stated in post title.
ITunes working completely fine up until a few days ago when I clicked on my Itunes icon and got the message:
The procedure entry point kCMByteStreamNotification_AvailableLengthChanges could not be located in the dynamic link library CoreMedia.dll
After clicking OK on this, the 'Itunes was not installed correctly. Please reinstall Itunes. Error 7 (Windows error 127)' message appeared.
I then reinstalled Itunes like it said, and despite saying that my itunes was now updated, I am still getting these error messages and am unable to go onto itunes. As i'm sure everyone can appreciate, I don't want to unistall itunes and quicktime etc, as I have a ton of songs on there that would take forever to download again. If there is nothing else I can do to solve this problem, obviously i'll need to attempt it.
Anyone with any other suggestions on fixing this problem?
Thanks!

Hello spearsap23
Start with the general troubleshooting in the first article below by clearing out the Temp folder and also remove iTunes and its related software. Then install iTunes from the second link below. Let me know if you run into any more issue and I will assist you further.

My iTunes won't open on Windows XP. iTunes.exe - Entry point not found, Error 7 (Windows Error 127)

When I open iTunes, I get a message saying under iTunes.exe - Entry Point Not Found, it says, The procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library SQLite3.dll. And I'm not talking about the AppleSyncNotifier.exe. Along with that, I get the message saying, "iTunes was not installed correctly. Please reinstall i Tunes." Error 7 (Windows Error 127). That's why I'm unable to open iTunes. I sure hope to see a solution to those problems soon.
I know I've mentioned this before, but I've now given a little more info to make my explanation more clear.

Try this one from Article TS3074

Why is my itunes not installing properly?
I installed itunes day before yesterday, I spent hours last night linking all my music photograph and movie files, its a new windows 8 laptop.
I plugged in my 64GB ipad 3 rebooted it and reloaded all the information I wanted on it, took hours... finally completed this this morning. After this I restarted the laptop to configure my icloud link for the laptop (which I installed last night while I was loading files, I chose to restart later)
on completion I turned my laptop off for a few hours, when I turned it back on I went to itunes to connect my iphone to do the same and I got this message:
iTunes exe - Entry Point Not Found
The procedure entry point
AVCFPlayerAppliesMediaSelectionCriteriaAutomaticallyKey could not

                                                                                           OK
then after pressing 'OK' the following message:
iTunes
iTunes was not installed correctly. Please reinstall iTunes
Error 7 (Windows error 127)
I went back to apple website to reinstall iTunes, first reinstalled it same again, then unsinstalled it and the reinstalled it, same again.
The same thing happened with my old lap top and I replaced it with this new one at the start of the week.
Has anyone any idea what is going on and how to rectify this problem, I am now going on 3 weeks without iTunes.

When I connect my new ipod nano to my laptop (using windows)I get an error message saying "itunes.exe - entry point not found" I cannot access my itunes , or download a new version. Any ideas what to do or what is causing this?

I have been given a new ipod nano to replace my much loved but old ipod. When I plug it into my laptop to sync it I get an error message stating "itunes.exe - entry point not found. The procedure entry point AVCFAAssetCreateWithByteStreanAndOptions could not be located in the dynamic link library

Error: iTunes.exe Entry Point Not Found

I recently upgraded my iTunes to the latest version and am now receiving the following error when I try to open it:
"iTunes.exe - Entry Point Not Found
The procedure entry point kCMByteStreamNotification_AvailableLengthChanged could not be located in the dynamic link library CoreMedia.dll."
and when I click ok it then gives me this error message
"iTunes was not installed correctly. Please reinstall iTunes.
Error 7 (Windows error 127)"
I have tried the following several times:
reinstalled/repaired iTunes
reinstalled/repaired QuickTime
reinstalled/repaired Apple Software Update
reinstalled/repaired Apple Application Support
none of which have worked. I get the error each time i try to open iTunes and then it just shuts down.
I have also tried to open iTunes in safe mode - per a recommended solution on another thread - which does not work. And I changed my control panel/quicktime/audio settings to safe mode - per a recommended solution on another thread - which does not work.
I have not added any other new software
I am on an old lenovo T61 laptop with Windows XP
Any and all suggestions would be greatly appreciated.
Thanks in advance!

Hi
I have tried to research these problems I am getting, but have not been able to resolve them.
1st is the above DDE Server Windows iTunes.exe - entry point not found.
This only occurs when I try to start iTunes.
if I click ok , several times, iTunes will start but slowly.
If at any time I have to reboot my computer I get
iTunesHelper.exe - the procedure entry point asl_add_log_file could not be located in the dynamic link library ASL.dll
if I click 3 times OK it goes away.
To this end I have uninstalled iTunes and rebooted my machine then gone to iTunes web site and downloaded the latest version.
Installing it but still get the same errors on reboot and trying to run iTunes
Anyone any ideas please.
I have a self build PC it has an Intel core 2 quad Q6000 @ 2.40GHz

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (If you've got XP, although the procedure is for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

After installing the current version of iTunes, I get an AppleSyncNotifier.exe - Entry Point Not Found error. It says "The procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library SQLite3.dll."

After installing the current version of iTunes, I get an AppleSyncNotifier.exe - Entry Point Not Found error. It says "The procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library SQLite3.dll." Kindly advice a process to get rid of this error, without losing my files on the iTunes.

Hi, I get the same error EVERY time iTunes updates.
I have to do the fix that is suggested in this topic (cut and paste the sqlite3.dll)
My Question:
Since this happens every time iTunes updates...... Do I have to remove SQlite3.dll from the "apple application support" folder....... so that the sqlite3.dll is only located in the "mobile device support" folder?????
It is getting really annoying to have to do the "cut and paste" fix every time iTunes updates.
Thank You,
Steve

ITunes.exe - entry point not found - VideoToolbox.dll error - can't open!

hello, can somebody please help me...
Everytime i open iTunes it comes up with this error message:
The procedure entry point VTSelectAndCreateVideoDecoderInstance could not be located in the dynamics link libary VideoTookbox.dll.
I've tried uninstalling, reinstalling, and deleting all iTunes and Quickime files and programs but it still wont work...
Please help me, Thanks!

*Replying to smyth_m*
So I followed the instructions and downloaded the newest version of iTunes like it told me, but after I did that, When I would attempt to get on iTunes an iTunes.exe - Entry Point Not found messege would come up. And it says The procedure entry point sqlite3preparev2 could not be located in the dynamic link library SQLite3.dll.
That's a different one, smyth. At the moment, you could try basiam's workaround from the following post:
http://discussions.apple.com/thread.jspa?messageID=10444196#10444196
... however, this could possibly cause trouble in its own right next time you upgrade iTunes, given that there will be a misplaced, older SQLite3.dll in system32 ... So be sure to remember you've got that dll down there, and if you get an odd message about SQLite3.dll when you try launching iTunes *after your next iTunes upgrade,* delete the old copy of the dll in system32 and see if you get a normal launch without it there.

Updated itunes and getting errors messages: iTunes.exe-Entry Point Not Found

After updating itunes, I get the message iTunes.exe-Entry Point Not Found. The procedure entry point AVCFPlayerEnableHardwareAcceleratedVideoDecoderKey could not be located in the dynamic library AVFoundationCF.dll.
Then another error message tells me: iTunes not installed correctly. Please reinstall. Error 7 (Windows error 127). I've tried to repair which looks successful until I try the desktop shortcut as well as going into the exe file in program files. Still the same message. Operating a windows XP service pack 3 with 32 bit. Help would be most appreciated.--No problems with itunes until this recent update.
