Q: iTunes 12.5.1.21 has stopped working. APPCRASH on Windows 7. WebKit.dll 7602.1050.4.5 error

iTunes64Setup-12.4.3.1 was working fine and no issue on Windows 7.

After update to iTunes6464Setup-12.5.1.21 or iTunes64Setup-12.5.1.21, APPCRASH happened.

Get 2x "iTunes has stopped working" and "Close program" messages when trying to view Store / App Store or view Account.

Possible only "Close program"...

Tried uninstall ALL Apple's software (with deletion of all related folders) and reinstall again but still same error!

ALL Apple's software mean iTunes, Apple Software Update, Apple Mobile Device Support, iCloud, Bonjour, Apple Application Support (32-bit and 64-bit).

Checked from Event Viewer:
