Q: iTunes.exe- Entry Point Not Found:  ?videoTracks@QTMovie@....

I've had the exact same problem on Windows 8 as well. I've tried uninstalling all the programs and restarting and reloading as well. It happened when i went to update the program.

Hey dude i finally found out how to fix it

Copy QTMovieWin.dll from c:\Program Files (x86) Common Files\Apple\Apple Application Support

and paste into

c:\Program Files (x86) \ iTunes

Hope that works for you dude.

naminegal, did you ever have Safari for Windows installed on your machine? Are there multiple copies of QTMovieWin.dll on your machine?

I tried this & iTunes works unless it try to access the store, the I get a message "iTunes has stopped working, A problem casued the program to stop working correctly.  Windows wil close the program and notify you if a solution is availble."  HELP!

Worked for me! Thank you very much.

From a conversation elsewhere it seems that ideally you would only have the one copy of QTMovieWin.dll in:

C:\Program Files\Common Files\Apple\Apple Application Support (32-bit Windows) or

C:\Program Files (x86)\Common Files\Apple\Apple Application Support (64-bit Windows)

You should find that if you remove any copy made in:

C:\Program Files\iTunes (32-bit Windows) or

C:\Program Files (x86)\iTunes (64-bit Windows)

that iTunes will work normally and that subsequent software updates don't cause this problem to reappear.

Hi turingtest2,

Yes I believe have hit upon the key to solving this problem. After upgrading to 11.1.4 I too received the "Entry point not found" error.  When I did a search on my C: drive for the QTMovieWin.dll file I found that it was present in 3 different directories but that the one that was in the C:\Program Files (x86)\Common Files\Apple\Apple Application Support directory had a more recent modified date ( January 20th 2014 ) than the other 2 versions. (I am running the 64-bit version of iTunes.) Therefore, following your advice, I deleted the file from the other 2 directories and tried starting iTunes again and voila it worked fine !  I must have previously copied the QTMovieWin.dll file into the other 2 directories in order to fix other iTunes startup problems but those copies are now out of date and when iTunes 11.4.1 tries to use them it throws up the "entry point not found" error.

So, I believe anyway, the best way to fix this problem (for both the short and long term) is to make sure that you only have the QTMovieWin.dll file in one directory ... i.e. in either

C:\Program Files\Common Files\Apple\Apple Application Support (32-bit Windows) or

C:\Program Files (x86)\Common Files\Apple\Apple Application Support (64-bit Windows)

Thanks for the follow-up.

gbiggles,

Do you have multiple copies of this dll on your system? In particular, do you have previous versions of dlls, like QTMovieWin.dll, in your C:\Program Files\iTunes that you have manually copied in?

If you had previously manually copied dlls from older versions of Apple software into your iTunes folder next to your iTunes.exe file, it would explain this problem. You should only have 1 copy of these dlls in the C:\Program Files\Common Files\Apple\Apple Application Support folder because that's the latest copy.

Toonz,

No, you should only have one copy of the QTMovie.dll file.

I didn't have previous versions because i unistalled all the itunes programs, making sure all their files were gone before i redownloaded itunes and then copied over the dll file.

Thanks. This worked for me.... LEGEND!!!!

this solved my problem too
