I'm having this same problem too. When I did the search for QTCF.dll or whatever only one thing came up and I deleted it and tried to open itunes again. Then a new message came up saying that there was no QTCF.dll found and I needed to reinstall it. So I restored it from the recycle bin.
How can I fix this problem!!! I cannot open itunes, and I can't uninstall itunes either because the popup pops up when I click to uninstall it as well!
This is soooooooooooo annoying cause my itunes was fine but then it randomly disappeared and I have no idea why, so i had to re download it and thats when all of these problems started.
I had the problem also where the QTCF file was only found in QuickTime and not under system32. The error message popped up after computer start up and would not be deleted even with Task Manager, and my iTunes would not start, so I uninstalled QuickTime and reinstalled it like you suggested, and my iTunes popped up. Everything is working perfectly again! Thanks so much!!
I finally found it in QTSystem (C:Program Files (x86)\Quick Time)
No, that's the correct one in a standard QuickTime installation, Wis. Leave that one alone for the moment.
Could you give us a quick summary of what you've tried to date? (There's a few different threads on this one, and I don't know which one you've seen. So I'm not sure what ground you've covered.)
I'm really hoping you can help me! I'm banging my head against a brick wall because the above error message keeps on popping up whenever I try to open iTunes.
I've uninstalled both iTunes and Quicktime and then reinstalled but to no avail. I then tried locating the QTCF.dll and adding an x, like I'd seen mentioned in another forum and still nothing.
I then searched and located the QTCF.dll file - the one in C:\WINDOWS\system32 and tried to delete that but it said that: Cannot delete QTCF: Access denied. Make sure that the disk is not full or write-protected and that the disk is not currently in use.
I'm seriously at my wits end and I'm no computer genius either. Can you please help me, as I really need iTunes to sync my iPhone.

Try dragging it out to the desktop first, melody. Are you able to get iTunes launching now?
If you can, try rebooting the PC and then deleting the file. Does that work, or do you get the deletion error message again?
Yes. That's the message I got when I tried to delete it.
I did what you suggested to someone else in an earlier forum. I've searched for the QTCF.dll file and got the following folder results:
Is there something I should try with these files?
Let's leave the file in C:\Program Files\QuickTime\QTSystem alone. Thst one is in the correct location.
We can try using Killbox to delete the one in \system32\
(I'd try the "Delete on reboot" option.)
I changed the file QTCF.dll to QTCFx.dll in the windows32 version and it seemed to make a difference. I was then able to open iTunes and then connected my iPhone but it then said that there was an issue with the Mobile Service Support but I was able to fix that no problem.
Thanks again for all your help :o)
To repeat others, Thank you thank you B Noir for your patience and easy to follow instructions!
I too had this common problem (QTCF_CFUniCharGetUnicodePropertyDataForPlane could not be located in the dynamic link library QTCF.dll).
After a thorough, complete search of both my drives the only .dll files found were in QT. I did not delete these.
Continuing the instructions/suggestions, I opted to delete QT only as I'm a bit gun shy about losing my iTunes library. I deleted QT, restarted my system, reinstalled QT, and CONGRATS! No more pop-up. iTunes works fine now.
I also had this problem, I uninstalled, then reinstalled, and it does not work. After a little investigation, I found a solution. The code QTCF_CFUniCharGetUnicodePropertyForPlane is a code in the QTCF.dll file. The current QTCF.dll in C:\Program FIles\iTunes does not have the string. I'll tell you how to fix it.
If you check it yourself, and open the old QTCF.dll file in iTunes folder with notepad PRECAUTIOUSLY, 'cuz you wouldn't wanna mess up the system file. Scroll down and you don;t see a text that says QTCF_CFUniCharGetUnicodePropertyForPlane. I'll give you advise.
First, download a new QTCF.dll here:
and store it where you cen find it easily. Open the DLL file with notepad WITH CAUTION! Scroll down and you'll see strings and codes. Search each line until you see QTCF_CFUniCharGetUnicodePropertyForPlane. If you find it, close it.
Now move the file to the iTunes folder and replace the old file, and you're done! Now open iTunes and it works well again!
