iTunes get stuck on outlook calendars while syncing

Everything was working perfectly. Then all of a sudden, itunes sticks on syncing calendars while syncing with iphone or ipad. Here is my senario:

Windows 7, Outlook 2007, up to date itunes, iphone and ipad. Outlook/apple addins both checked. Restart computer, restart outlook, restart itunes. Connect iphone with usb, everything in "info" checked. Start sync. Backup ok, then contacts, then it stays on calendars! Cancel sync. Disconnect and reconnect iphone. Message pops up saying something about app data and sync services. Click OK. "Info" has nothing checked and in calendar section it says I need to install outlook. I tried reseting sync history but clicking the button seems to do nothing. I did update itunes lately but everything worked after that for a while. Please help!

Dell, Windows 7

By any chance are you running any Eset security software products (like Nod32) on that PC?


If so, there's a couple of alternatives.


Either try the procedure in Samoreen's post:

Or, see if you can get hold of the Eset beta addressing the problem. As Samoreen notes in another post:


ESET have a workaround for this issue. They gave me access to a test version of the HIPS module and this fixed the problem. So I could re-enable the ESET_OPTIONS environment variable (although I still consider that it's a questionable idea). I upgraded to iTunes 11.1.5.5 and there was no problem.


So maybe you should get in touch with ESET support and request the new module ? Just send a message to Marcos in the ESET forum.
