Problem with Itunes 9.1 on Windows 7

Question

Hi all
Problem with the 9.1 version of itunes. I download the update and everything went ok and till i reboot the pc and gave me this messages. "Apple sync notifier "The program can't start corefundation.dll missing from this computer".
Trying to fix the problem i uninstall itunes, Quick, apple application device, apple mobile device, and software update and reboot the pc and reinstall everything. This time everything went right and no more message but now if i click to open itunes it not runs and safari is making my computer slow and it freeze for seconds.
Any idea what could be my problem?

Same problem here. Running the iTunes network diagnostic doesn't enlighten me: it tells me that connectivity to the iTunes store is fine. My firewall tells me that when iTunes starts it attempts to connect to "http://wpad/wpad.dat" which of course fails because the unqualified domain name gets my local domain added to it (and I don't have a host called ipad on my network).
Here's the report; in case it helps Apple figure out what's wrong:
