**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.

    I had this exact problem.  I'm not sure what fixed it, but I did 2 things.  The first was that I opened the registry, like MitchellCartwright said, above.  I didn't do anything once I was in the registry.  I just opened it, looked around and closed it.  This is probably what fixed it since it worked for Mitchell above, so try that first.  And remember LET THE INSTALLER RUN UNTIL IT FINISHES. 

    If that doesn't work, the other thing I did was the following:

    1.  Go to Programs and Features in the Control Panel.

    2.  Sort by Publisher so you can see all of the Apple products.

    3.  For each of these:  ITunes, Bonjour, Apple Software Update, Apple Application Support, and iCloud do the following:

         a.  Select the application

         b.  Hit Repair

         c.  Hit Uninstall

    For some of them (I think iCloud), you had to hit "Change", then select "Repair", then hit "Change" again and then select "Uninstall"

    4.  Restart the computer

    5.  Download the newest version of ITunes and install it.

    6.  Remember ->  LET THE INSTALLER RUN UNTIL IT FINISHES.

    I had been unable to install windows updates for over a year until I did the above regedit.

    Thanks a lot. All updates automatically installed during reboot. 

    Still running SFC Scan but I will reply again if Itunes install works as well.
