iTunes 11 crashes when I open the store.

YES. THANK YOU.

You ROCK!! fixed the problem

This one did it for me.

So crazy that in 2013, I have to copy a DLL to another directory or munge around in the environment variables to get [nearly] ubiquitous software to work. But, that being said... the HACK that you awesome people found, works perfectly.

Worked for me!!

What worked for me was CUTTING (not copying) the QTMovieWin.dll from c:\program files (x86)\common files\apple\apple application support\ INTO c:\program files (x86)\iTunes. My iTunes now works. I'm finally able to check my account without having iTunes crash! I had tried everything without any luck, including rolling back the HD 4000 display driver, disabling the HD 4000 display driver, changing the PATH variable, and uninstalling iTunes and Apple software and reinstalling. Thank you!

Thank you TempDC! I had also tried the video adapter fixes with no luck. The cut and paste as described has my iTunes working again! Excellent Job.

Hello lionhartz, after hours i find your solution.

Excellent work!!

Have a nice day!

This suggestion also solved the problem for me too.

I can't find that QTMovieWin.dll file. I go c:\program files (x86)\common files\apple but there is no apple application support.

Realy thanks man, this suggestion solved my problem.

Thanks brother!

I had the same problem after upgrading to Windows 8.1. Thanks a lot for this hint, it solved the problem.

But it really shows, how badly iTunes for Windows is written. I wonder why Apple does not use the billions of cash they have and re-write that software from scratch...

another satisfied customer, thanks! i'm on a new laptop and had successfully accessed the store when docked and using a monitor. itunes crashed when i tried to get undocked but adding the variable to PATH did the trick.

So... after going through this I found the fix posted by lionhartz, but didn't understand how to actually do the fix, after reading part of page two, I found the post by Range Ruler on August 30, 2013. Went to c:\program files (x86)\common files\apple\apple and found QTMovieWin.dll, checked to see if it was something I needed to edit in it, which there wasn't. On a random thought of, "Maybe QTMovieWin.dll got corrupted." I deleted it and then emptied the recycle bin. Now iTunes wouldn't launch at all, so I redownloaded and reinstalled iTunes. After reinstalling iTunes the store opened perfectly with no problems. So yet another way to fix this weird error for everyone. Hope it helps.

After scrolling through all of this, I decided to just delete QuickTime which fixed the problem at once with no reboot of my computer necessary.

Can't believe that this problem has been going on for so long and happens so abruptly and suddenly (I've been using iTunes without problem since its last update on 16 May 2014) and Apple still hasn't fixed the issue!
