Good luck other people with the same problem.

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:

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.

2010-02-27T17:56:00+00:00 There has to be a solution other than reinstalling windows.
I’m running windows Vista and having the exact same problem as “dnlhrd”. I tried installing “vcredist_x86.exe” multiple times and keep on getting the same error message: Error 1935…
It’s so frustrating spending hours and hours of my life on something that should take only a few minutes… MS PLEASE HELP!

2010-01-11T23:14:29+00:00 I just tried installing the vcredist_x86.exe again and it stops on the step on the third go through the progress bar (one stage is checking previous installs or something like that) and freezes. Task manager can end it but I am then presented with the message that Windows installer has stopped responding. Leaving it alone for half an hour or so gives the error message

Please refer to Help and Support for more information.
Trying to run the install after this gives the message that another program is being installed and I must wait until that installation is completed. A restart is needed before trying again.

2010-01-11T22:57:32+00:00 The installer freezes every time. I have left it alone for hours on multiple occasions and it never finishes. Task manager closing it responds that Windows Installer has stopped working and must be restarted. From there the computer has to be restarted before I can try and install it again.
