Hello and thanks in advance for your time! I have been having this problem for a while and I need to fix it as I cannot properly use iTunes to update my iphone or anything else..... Every time I go to update iTunes it comes up with this message box:
could not open key:
UNKNOWN\Components\2FBF74B8EFDC1654F863E8
3452159AC3\46B5A9879DD95AB419A50FCFA0B1B7
EF. Verify that you have sufficient access to that key,
or contact your support personnel.
