Hi, i have trouble with itunes. With the new update, i was unable to use my itunes. "Apple mobile Device failed to start. Verify you have sufficient privilege to start system". After that, i uninstall/install Itunes...and same message. Any help?
I have had this same problem and it was resolved by rolling back to an earlier version of iTunes as you suggested (thanks), however, now that ios has updated on my iphone 5S to 9.0.1, now iTunes says I have to update iTunes to the latest version in order to connect to the phone. Help!! I am pretty sure if I try updating iTunes again, I will get the same error and be back to square 1. Any other ideas?
This is a slightly expanded version of my earlier boilerplate. If you still have trouble posting back the exact error message should allow me to get you any relevant advice which isn't already captured in the user tip.
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 the iTunes 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 and device backups should be unaffected by these steps but there are links to backup and recovery advice should it be needed.
If the issue persists and you have a 64-bit system try the for older video cards version which is a 64-bit installer for mostly 32-bit code, similar to all 64-bit versions of iTunes up to 12.1.
If you've tried the above without success then see the method in Install missing components. What component fails to install, and what error message does it give? See this post for steps to produce detailed logs of the installation which may reveal why iTunes won't install. Look for keywords such as failed or error.

That was the only one alternative for me. I tried all, clean even register and nothing.
I have installed on Windows 7 64bits and works! : iTunes 12.0.1.26 for Windows (64-bit) - iTunes64Setup.exe (2014-10-16)
