Do you get an error message if you try to launch iTunes? If so, what does it say? (Precise text, please.)

with apologies to playerpro, since I don't know his/her results.  But I have had the 'same' experience of itunes no longer starting.  no error message.  Just double click; the blue circle; then nothing.

I, too, have uninstalled and reinstalled several times.

I've tried several 'fixes' that I found suggested in earlier posts.....but they were all a year old so I have no idea whether they would even be considered for current versions.

l am on a 64 bit pc running Windows 7, all up to date.

I, too, did the update to itunes 11.... :-(

Help would be appreciated.

I have the same troubles with same OS and the same itunes...
