iTunes fails to start up when I open it. When I open it I get the following error box, "The iTunes application could not be opened. An unknown error occured. (-200)" Anyone know what -200 is? Or how to fix it?
Macbook Pro, Mac OS X (10.7)
I just got the same problem on two computers. I use one multiple times a day, but I touch the other one infrequently so it may have happened any time in the last few weeks.
The problem just disappeared on one machine. On my primary MBP, it is still a problem, but I also notice an error that appears in my browsers (Flash sound apps) and Blackboard Communicate (a webconferencing tool) that they can't connect to the speaker. One time, I got a message to disconnect my headphones, but I had none connected.
Experienced the same issues; iTunes won't open (error 200) and no sound with flashed based apps; with my Macbook (late 2009) after upgrading to Lion. Reset the PRAM and everything is working fine.
To reset the PRAM: Shutdown Mac. Hold down: Command, Option, P, R all at the same time, and press Power button. Keep holding down the buttons until Mac restarts and you hear the second startup chime.
Note: Make sure your software is up to date.
I can confirm that resetting the PRAM worked for me as well. Thank you for providing a useful and correct answer. I had to go through many posts before I found this one.
Resetting the PRAM also worked for me. A simple and easy answer, thank you!
THANKS SO MUCH FOR YOUR HELP!
