Entry point errors can usually be fixed by deleting the offending dll, then repairing the component(s) it is part of from the programs and features control panel. CoreAudioToolbox.dll is part of Apple Application Support and can normally be found in:

C:\Program Files\Common Files\Apple\Apple Application Support and/or

C:\Program Files (x86)\Common Files\Apple\Apple Application Support.


For general advice see Troubleshooting issues with iTunes for Windows updates.


The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.


The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try theiTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.



Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

Using Windows Explorer browse to each of these locations:

  • C:\Program Files\Common Files\Apple\Apple Application Support
  • C:\Program Files (x86)\Common Files\Apple\Apple Application Support


If one of them doesn't exist don't worry about it. When you open either of the folders look for a file called CoreAudioToolbox.dll, click on it to select, then press Delete on your keyboard to delete it. Confirm that you want it deleted. Again, don't worry if it isn't found, just try the other folder.


Now open the Windows Control Panel, then the Programs and Features control panel inside that. Locate the entry/entries for Apple Application Support. You may have both a 32-bit and 64-bit version. For each that you have select it and click the Repair button.


Try running iTunes now.




If it still doesn't work follow this link to thesecond boxof the Troubleshooting issues with iTunes for Windows updates tip and work though it to remove all Apple software components and then cleanly reinstall it.



In some cases the alternate version of iTunes found at iTunes for Windows (64-bit - for older video cards) may be stable on your computer if the full 64-bit version isn't.



Read the other advice in the user tip if required.
