Hi, Are you trying to install iTunes 9 or 10? Sometimes killing the registry entries for the software will fool the installer into working again. If you're only trying 9 and want 10, I hosted it for a friend at: www.patwanet.co.uk/dl/apple HTH. _______________________________________ Have a pleasant day, Kind Regards and Best Wishes, Hussein.

I get a message that the Windows Installer service cannot be accessed, and am told that this can occur if it hasn't been installed correctly. Unfortunately the iTunes update appeared to get so far because some of the files have been modified or removed meaning it won't run. When I try and uninstall iTunes to start again, I get the same message. When I try running the iTunes setup programme I am told that a problem caused the iTunes installer to stop working. I have downloaded the setup file a few times with the same result. I am running Vista Home Premium on an HP Pavilion DV9000 series. Thanks for any help anyone is able to offer. Ed
