**Original Title** An error occurred during the installation of assembly 'Microsoft.VC80.CRT,version="8.0.50727.4053",type="win32",publicKeyToken='1fc8b3b9a1e18e3b",processorarchitecture="x86". Please refer to Help and Support for more information. HRESULT:0x800736FD

Windows xp to Windows 7 32 bit install of home premium.  iTunes will not install.  The installation freezes at Publishing product information, gives this error message:

An error occurred during the installation of assembly 'Microsoft.VC80.CRT,version="8.0.50727.4053",type="win32",publicKeyToken='1fc8b3b9a1e18e3b",processorarchitecture="x86". Please refer to Help and Support for more information. HRESULT:0x800736FD

stays frozen and eventually claims iTunes was installed correctly.  Opening iTunes produces an error stating that Apple application support is not installed (Apple application support/Apple mobile device support are not on the computer).  (Bonjour, Quicktime, and Apple software update are there).  I have uninstalled the programs which goes fine but nothing I try can get itunes to work.  I tried installing itunes 8.0, running on a different administrator user, running as administrator, stopping all programs from running, and installing while offline.  I read that there might be a problem with Microsoft Visual C++ 2005.  My computer shows  both Microsoft Visual C++ 2005 Redistributable andMicrosoft Visual C++ 2008 Redistributable - x86 9.0.21022.218 on it.  I tried installing the Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package ATL Security Update file vcredist_x86.exe found at **http://www.microsoft.com/downloads/details.aspx?familyid=766a6af7-ec73-40ff-b072-9112bab119c2&displaylang=en#filelist**

but it freezes at around 100% of completion. 

This is where I am now.  My Windows updates have not been failing and my system is up to date.  I do not know what to do as I need this program installed in order to use my phone.

Thank you for your time and any assistance you might be able to offer.

    To those who didn't have the Registry Key already in the registry:

    Yes, you can just create the key.

    Use the following steps:

    1. Open regedit and go to:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control

    Right-click on a blank spot on the right-hand side and reate a new DWord Value called RegistrySizeLimit


    Set the value to: FFFFFFFF (4294967295)

    1. Reboot
    2. Open a command prompt as administrator and run SFC /SCANNOW to check the integrity of system modules.
    3. Install pending windows updates

    This worked for me on a Windows 7 64-Bit machine.

    Hope this helps.

    Just to add to this, experienced this error on vista when installing itunes.  After much searching and head scratching I've traced it back to spybot search and destroy resident protection.  Disabling the protection results in the installer completing successfully.
