Hi,

I've been trying to use 64-bit installer and have tried to disable my anti-virus software. when I am trying to install Itunes but I get the error message "Could Not open key: Could not open key: UNKNOWN\Components\.........." I have removed previous versions of iTunes and deleted all the previous user and I am the administrator accounts of the PC. Am I missing something?

I am currently having this same error when trying to reinstall iTunes 9 x64. When first installed, the installer froze. I uninstalled it and reinstall successfully, but I was wrong about "the necessary software to communicate with iPods and mobile phones has not been installed correctly." It offered to repair, but this seems to do nothing.

To remove your error, Go to that registry folder, instead of simply adding "everyone" permissions, click Advanced -> Auditing -> Add -> Advanced -> Find Now -> Add and manager & everyone -> back to the audit section -> check "Replace all existing inheritable ..." -> Click the effective permissions -> Select -> Advanced -> Find Now -> Organize -> make sure everything is checked and do for everyone, so -> click until you exit the Permissions section -> then again on permits and undo everything you've done -> try to access the keys and see if they can help them.

Hey Guys,

I had the same problems with the modifying of the UNKNOWN/Components/... registry stuff.. It came down, as SimonBoss said, to security settings on a key in the registry.
