Itunes 11.3 won't even start

I had the same issue and here is how I resolved it.

Make sure that the BONJOUR service is running and uninstall QuickTime Player 7 if you have it installed.

Also, set Bonjour to allow it to interact with the desktop.

After that iTunes 11.3 on Win7 64 Bit works as it should.

Kraftwerk, I want to thank you for your post! This fixed my issue today. After downloading itunes 11.3.0.54 I was having massive issues with itunes freezing up and hogging resources. I am running win 7 64 bit and have a massive podcasting stream. I brought up task manager and force closed the application 12 times. I tried reinstalling itunes. I am leaving in two hours for vacation and I just wanted all my newest podcasts. What a relief that your post appeared. This saved me from throwing my computer out the door! thank you, Thank You, THANK YOU!!!!

😍😁🙂

I am so glad I was able to help. Have fun on your vacation!

Hi Kraftwerk

Think I'm having the same problem as Renee

Installed latest version of iTunes on my Windows 8.1 (fully updated/upgraded), but iTunes won't start.

Hooking up my iPad to my PC results in a question on my iPad about trust, which I confirm.

Bonjour service is running. Any idea?

Thanks for thinking :-)

Hi,

I do not have Windows 8.1, so I may not be able to help much. Did you check that Bonjour is allowed to interact with the desktop?

Otherwise have you tried doing a repair using the iTunes installer?

Thanks for your response :-)

Yes I altered the services and Bonjour is now allowed to interact with the desktop.

Will try to perform the repair action. Thanks for the hint.

Hi Kraftwerk,

Your hint worked well, upto a certain point :-)

Performed a repair of the freshly installed iTunes and indeed, after the restart of the computer it started like a charm. I could perform a backup of my iPad and then I closed iTunes, did some other things and restarted iTunes to update my iPad's iOS.

iTunes didn't started. Performed a shutdown and after the shutdown started iTunes. Worked again. Stopped iTunes, checked Taskmanager, no running processes for iTunes, restarted iTunes. No iTunes.

I'm more then confused. No error messages, nothing in my eventviewer, just nothing.

Any idea which direction I now have to go :-)

I have found that on my work laptop for some reason Bonjour keeps getting switched off, so check that.

Other than that, I am kind of at the end as well. Do you have anything else running that may cause a conflict?
