I am using a HP Laptop running Windows 7 and have installed iTunes 12.1.2. and it does run without my iPhone5S connected. But once I connected my phone to iTunes, I get the following message :
"iTunes has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notifty you if a solution is available."
Here is a screen shot as well -
I have tried all of the following at these links - https://support.apple.com/en-us/HT204095 and https://support.apple.com/en-gb/HT201252 and https://support.apple.com/en-gb/HT203206 among others.
How can I fix this problem so I can be able to use iTunes with my phone connected, I need to do a backup and it won't let me. Please help!
