  1. Hi all

    I have tried to install itunes for windows 7 64bit professional with no luck. i get three error messages as follows:
    1) could not open key: unknown components\DA42........
    verify that you have sufficient access to that key.

    2)Service apple mobile device failed to start , verify that you have sufficient access to that key.

    3)Apple application support was not found. Apple application support is needed to run itunes. Please uninstall then reinstall itunes.
    Error 2 ( windows error 2)

    the programs shows up in the list of programs when i uninstall it, but it just wont open.

    I have tried every link that i could find on the topic. If anyone else has had this problem and found a solution, please post it.

    Many Thanks

    Warren

    Use IE and go to the iTunes download page. If you do it in FF or Opera I think you end up getting the 32bit one, which doesn't work in 64bit Windows (one of the few 32bit installs that won't, likely because of some hardware drivers they put in).

    Did you use IE64? If so, then I'm not sure.

    Just out of curiosity, when you ran the iTunes installer, did you try to right click the installation file and select "Run as administrator"? It's a long shot, but worth a try.

    yeah i have tried it as an administrator but that also does not work iether...
    i have run it through IE, chrome, from different websites... the 32bit version the 64bit version.... and nothing...
    there has got to be a solution somewhere..
