hello wont let me connect to itunes keeps comming up with unknown error

Are you getting an error message number with that Unknown error? If so, what number are you getting, please?

I had this exact same problem. I found this fix and it worked for me.

Step 1:

Browse to C:\Program Files (x86)\Common Files\Apple\Apple Application Support and copy the filen named QTMovieWin.dll.

Step 2:

Browse and past that file into C:\Program Files (x86)\iTunes.

Hope this helps you. I wish I could remember where I saw this originally so I could thank them.

Good Luck.

Anthony
