Itunes 11.4 crashes when syncing apps to ipad / iphone

Question

hey everyone, maybe the knowledge of the many may help, as I am rather at a loss right now!
after installing itunes 11.4, my trouble started! running 64 bit version on windows 8.1 - and latest iOS on both devices
all windows updates installed, all drivers for whatever is running on this machien are also up to date
connecting either ipad or iphone to computer, when itunes starts to sync, it gets to the point of "syncing apps to iPAD", it tries to add the first app - and crashes for good!
and yep, I went thru all the suggested thingies recommended on here:
iTunes for Windows Vista, Windows 7, or Windows 8: Fix unexpected quits or launch issues
http://support.apple.com/kb/TS1717
windows pops up "itunes has stopped working" ... so I headed over to the Windows Event viewer, and for the moment, itunes crashes, I find these two entries in the log file - tried a search on here, google as well, to no avail:

Answer 1

Also using iTunes 11.4 on Windows 8.1 Enterprise 64-bit. Crashes in the "syncing apps" stage. Happens on two different user accounts, one using an iPod Touch and one using an iPhone 5.
Clean uninstall/reinstall doesn't make any difference. Safe mode doesn't make any difference (no plug-ins installed).
Stack trace shows an unknown routine in iTunesMobileDevice.dll calling Microsoft C++ runtime routine _wstat32i64 with a null name parameter. This is definitely an iTunes 11.4 bug.

*int _stat(name, buf) - get file status info
*Purpose:
*      _stat obtains information about the file and stores it in the
*      structure pointed to by buf.
*      Note: We cannot directly use the file time stamps returned in the
*      WIN32_FIND_DATA structure. The values are supposedly in system time
*      and system time is ambiguously defined (it is UTC for Windows NT, local
*      time for Win32S and probably local time for Win32C). Therefore, these
*      values must be converted to local time before than can be used.
*Entry:
*      _TSCHAR *name -    pathname of given file
*      struct _stat *buffer - pointer to buffer to store info in
*Exit:
*      fills in structure pointed to by buffer
*      returns 0 if successful
*      returns -1 and sets errno if unsuccessful
*Exceptions:
