I had the same problem. Finally went into Programs - Common Files - Apple - Mobile Device Support - I had to delete this folder, then rebooted & reinstalled and now Outlook works again.

Thank you turingtest12.  I did the steps as outlined in your post and it worked for me as well.  I'm on Windows Vista.

I went through the account creation process just so I could express my thanks, turingtest2. This problem was driving me crazy -- thanks for the help. Worked for me on PC using Vista 64-bit.

You're welcome.

Thank you!!!  This helped 100%

had the same issue as you couldnt uninstall the Apple Mobile Device Support but it seemed that as long as i uninstalled the updater and itunes and rebooted/reinstalled itunes that it fixed the problem

Your solution works for me!!!  You have saved us a lot of time.  Thanks very much!! 

I just found this fix and it worked.  Took me 5 minutes.

Had to go to control panel - Programs and Features - and uninstall five items in order.  Then reinstall iTunes.

Thanks tt2! All went perfect!

Thank you turingtest2 .. followed your instructions on uninstalling all those apple programs and I am once again up and running.   It is a shame that as of late whenever I see an itune upgrade I hesitate and put it off as long as possible.   BN

Many thanks to turingtest2 - total genius - I was getting a missing MSVCR80.dll file and the error 7 message.  I did what you said and it worked like a dream.  Thank you x

You're welcome.
