Hi ikaizen15,

I see that you are getting an error when attempting to install an update to iTunes on your Windows PC. I have an article for you that references your specific error code, and it can be found below:

If you can't install or update iTunes for Windows - Apple Support

Since you also mentioned that the Apple Mobile Device Service was reporting an error as well, here is an article that will help you restart your AMDS:

Thanks for being a part of the Apple Support Communities!

Cheers,

If the above steps haven't helped try installing:

iTunes 12.1.0.71 for Windows (64-bit - for older video cards) - itunes64setup.exe (2015-01-28)

which is a 64-bit installer for a 32-bit core program, similar to previous 64-bit releases of iTunes, or roll back to:

• iTunes 12.0.1.26 for Windows (32-bit) - iTunesSetup.exe (2014-10-16)
• iTunes 12.0.1.26 for Windows (64-bit) - iTunes64Setup.exe (2014-10-16)

as appropriate.
