After a recent bios upgrade itunes will hard freeze everything while trying to load corefp.dll (ran it through windbg, this is where it halts). It does not accept any input, all displays freeze - the only solution is to reboot manually.

After further testing I tried both removing and renaming corefp.dll - this allowed itunes to load properly, no system lockups. Of course this caused a new problem, any iphones/ipods are unable to sync with itunes due to the fact that the Coref(air)p(lay).dll was not loaded. I can use pretty much any itunes fuction save syncing devices.

At the moment I cannot downgrade my bios, so my only option would be to wait for Asus to fix whatever they broke, or see if Apple can offer a solution.

Does anybody have any suggestions or ideas of how I could fix this problem?

    Just doublechecking ... after removing the copy of CoreFP.dll, did you try doing a repair install of iTunes to replace the CoreFP.dll and then seeing if iTunes both launched and synced with the new CoreFP.dll in place?
  • Shenkhar Level 1 Level 1 (0 points)
    Yes, I removed it and did a repair install, still halts when corefp.dll is loaded. I did a complete uninstall, re-installed - the same problem occurs. iTunes will not load and causes a hard stall if corefp.dll is present.

    Many thanks.

    ... If you're game for some basic-principles troubleshooting ...

    A subset of CoreFP.dll troubles seem to be related to security software interference. What security software do you have installed on the PC? (Firewall, antivirus, antispyware?)

    Even if it isn't installed now, has a Symantec security product like Norton *ever been* installed on the PC?
  • Shenkhar Level 1 Level 1 (0 points)
    Nope, this is a brand new format with no security features installed aside from windows defender, which is disabled. The only thing that I can imagine that might interfere would be punkbuster.

    Okay ... just quickly checking on some background information. Prior to the BIOS update, was the PC authorised to play any purchased content? If so, was she deauthorised prior to doing the BIOS update?

    (I'm thinking about a rarish sort of combined problem relating to multiple authorisations and a dodgy iTunes configuration file.)
  • Shenkhar Level 1 Level 1 (0 points)
    I have purchased music and iphone applications on the pc, none of which had DRM on it. I assume this means that it had no authorizations on it. It it is of any relevance, I had tried cleaning out the itunes config files, as well as any playlist databases and with no success in solving my problem.

    Doublechecking that we're talking about the same thing ... were those the configuration files mentioned in the following document?

  • Shenkhar Level 1 Level 1 (0 points)
    Yes that is correct. I followed pretty much every troubleshooting method in the apple support documentation.

    Ahhh ... is it a systemwide freeze or a user-account specific one? (My guess from the sound of things is that we've got a systemwide freeze going on, but my guesses about that have been wrong more than right in recent weeks.)
  • Shenkhar Level 1 Level 1 (0 points)
    It is a system wide issue, happens on all user accounts.

    Thanks again.

    I'd like to doublecheck one of the procedures you've been through. Unfortunately, the *Verify iTunes and related components are completely uninstalled* section from the following document:

    [Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7|http://support.apple.com/kb/HT1923]

    ... is not currently accurate for 64-bit systems. (There's program files and folders in \Program Files (x86)\ as well as in Program Files, and there's some componentry in \SysWOW64\ instead of \System32\, for example.) So my worry is that some old componentry from the previous installs may have been left behind, and issues with that are continuing to ramify through to your CoreFP.dll.

    So it might be worth trying a complete uninstall/reinstall again, only using the following set of instructions at the *Verify iTunes and related components are completely uninstalled* stage of proceedings.

    (1) Restart your computer.
    (2) After the computer restarts, open Local Disk (C:) located in Computer or whichever hard disk your programs are installed on.
    (3) Open the Program Files folder.
    (4) Right-click the iTunes folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion.
    (4.5) Right-click the iPod folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (5) Right-click the Bonjour folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (6) Open the Common Files folder.
    (7) Right-click the Apple folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (8) Open Local Disk (C:) located in Computer or whichever hard disk your operating system is installed on.
    (9) Open the Program Files (x86) folder.
    (10) Right-click the iTunes folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion.
    (11) Right-click the iPod folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (12) Right-click the QuickTime folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (13) Right-click the Bonjour folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (14) Right-click the Apple Software Update folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (15) Open the Common Files folder.
    (16) Right-click the Apple folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (17) Open Local Disk (C:) located in Computer or whichever hard disk your operating system is installed on.
    (18) Open the Windows folder.
    (19) Open the SysWOW64 folder.
    (20) Right-click the QuickTime file (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (21) Right-click the QuickTimeVR file (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
    (22) Right-click the Recycle Bin and choose Empty Recycle Bin.

    After that version of the uninstall/reinstall ... any better luck with the CoreFP woes this time around?
  • Shenkhar Level 1 Level 1 (0 points)
    Nope... system still locks up if I leave the base install untouched. As soon as I take corefp.dll out of the equation, it magically starts working again - save the ability to connect to iphones or ipods.
  • b noir Level 9 Level 9 (72,020 points)
    Okay. Have you tried an sfc /scannow just to check to see if there's any subtle operating system file damage in the mix somewhere?

    Ran a SFC, it did not find any integrity violations.
