Error installing itunes

The message "An error occurred during installation of assembly 'Microsoft.VC80.CRT, type="win32", version="8.0.50727.6195", publicKeyToken="1fc8b3b9a1e18e3b", processorArchitrcture=..." may occur because a particular library file is not included in the distribution package supplied with iTunes or won't install for some unspecified reason. Installing the Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package MFC Security Update before attempting to reinstall iTunes may help.

There are three files to choose from so you need to select the one that matches the processor architecture of your system, which should be noted in the error message.

• vcredist_x86.EXE - 32-bit systems
• vcredist_IA64.EXE - Itanium processors
• vcredist_x64.EXE - other 64-bit systems

HRESULT: 0x80070BC9

These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.

Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?

If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? Are they also 80070BC9, or some other number? (If they're another number, what number are you getting?)

I have the same issue...

I recently updated my iPad Pro 12.9 to the latest IOS 10.2.1

I then plugged it in to my laptop to transfer from files.

I was then told than in order to access my iPad I would need to update my iTunes software to the latest version 12.5.5

I'm running Windows 10, but like many customers I'm getting an error message (show below) that I am unable to get around no matter what I try.

So I am now stuck with a laptop and an iPad that I cannot use properly. I'm really upset about this. What is Apple doing and what can I do to fix this?

The error message is:

An error occurred during the installation of assembly 'Microsoft.VC80.CRT.type="win32",version="8.0.50727.4053".publicKeyToken="1fc8b 3b9a1e18e3b",processorArchitecture="amd64"". Please refer to Help and Support for more information. HRESULT: 0x80070BC9

I tried updating my pc, and it said there were no updates. So, I went into my history and it isn completely empty.
