    I also have problems just like you, but in order.

    Fist .      An error occured during installation of assembly "Microsoft.VC80.CRT

    Second. Apple mobile device failed to start. Verify you have sufficient privileges to start system services.

    Now just wait for apple confirmed that bug, and fix it.

    Hey guys


    I am facing same issues - infact as mentioned by stevensncu i've got same errors - error 2 followed by error 1.


    Post back if any luck.

    I get exactly the same. I removed I-Tunes and now it won't reinstall, as it's version 10.5. No IOS5 either.

  • stevensncu Level 1 (0 points)

    I've read more than a few discussions and have tried the "fixes" they say work and still have had no luck.  I removed itunes and all the components and have given up on downloading it.

    Hey guys


    After spending a long time I got fed up and did a workaround. I download & installed iTunes 10.5 on my other laptop (which has win 7 - 64 bit) transferred all my apps on that machine then updated to iOS 5. This worked :)

    similar problem.

    MobileDeviceHelper does not work immediately when i open my iTunes.

    I can play music but if i connect my iPhone to my PC itunes just froze.

    Same here, i just got the iphone 4s and im trying to add music to it through my Macbook Pros itunes and its installs and downloads but it doesnt update for some weird reason and my itunes has to be 10.5 or my iphone wont sync i dont know what to do!

  • navyanimals Level 1 (0 points)

    I also can't use iTunes since the update.  The iTunes store doesn't ever load but I can download apps updates and podcasts.  The iPhones don't get past the backup stage so I can't update to the new IOS 5.

  • ManjotFromToronto Level 1 (0 points)

    It is the 10.5 update that is messed and should be fixed.

  • Kibosh325 Level 1 (0 points)

    I am having the same problem. Started when windows 7 PC hung during iPhone synch/update. iTunes and safari will no longer open with two errors which are shown above.  Apple updater cannot repair safari and "rolls back" install attempts.  Tried uninstalling all apple software, and related apple folders with no luck.  Cleaned registry, tried ms config suggestion, completed apple troubleshooting, no luck.  I was told it is a Microsoft issue.  My PC won't install updates now either.  Incredibly frustrating, and no iOS 5.
