I have tried several time not to install iTunes on my computer and get the same result. A dialog box come up labeled iTunes and it says: "There is a problem with this windows installer package. A DLL required to complete could not be run." I have tied running anti virus and malwear. I have tired running it with my a antivirus program turned off. I won't know what to do because it foes not tell me whar DLL is involved/ Can anyone help me get iTunes installed on my pc so I can use it with my Ipad mini and my Iphone. Thanks
