I've been struggling with this for a couple of hours now.
Whenever I sync / restore my iPhone or iPad, iTunes throws back this message.
I have followed the guides of previous questions, but nothing is working.
I have updated all software, checked all my security apps, uninstalled, reinstalled, tried in safety mode and moved .dll files.
I have literally tried EVERYTHING and yet I'm still unable to sync my devices.
PLEASE help.
iPhone 6s, iOS 9.3.1
Try Fix unexpected quits or launch issues in iTunes for Windows - Apple 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 the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with 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.

HI.
As mentioned in my original post. I've already tried all of these fixes. Nothing works.
What version of iTunes are you running?
What version of Windows? 32-bit or 64?
Do you have anti-virus or firewall software? If so what?

I have same issue and I am using iTunes 12.3.3 for Windows (64-bit) (Windows 10). Only have Windows Defender. And like @cathelynneI have iPhone 6s, iOS 9.3.1
I seem to have identified the source of my problem. It is network/firewall related I believe. I put my computer into flight mode and managed to connect my iPhone without iTunes crashing. The thing is I need to use my computer with Internet on as well as have my iPhone connected to iTunes so any ideas how I can bypass this issue would be great.
Does your computer use a proxy connection? This seems to cause particular problems with iTunes 12.3.3.
Try rolling back to the last build of iTunes that worked for you. See iTunes installers for download links. If you're rolling back from 12.3.3.17 to 12.3.2.35, for example, then you'll also need to roll back the database in the way described in Empty/corrupt iTunes library after upgrade/crash. The tip includes suggestions for reintroducing any recent purchases so at worst you lose a few playcounts and/or a recently created playlist.
