Hey Paddyl180,

Thank you for thinking of Apple Support Communities for your support needs.

So iTunes is stuck now. It won't open and gives error 7 and 127 when trying to update.

Error 7 is discussed in this article. Please check it out.

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

Note it has links to deeper steps along the way.

Regards,

Nubz

The issue was resolved after about 4 hrs. you need to remove some of the apple programs in a particular order if you do a search on the internet it will tell you the sequence. You will then need to reload an older version of iTunes search for DL1784 Apple and download this. Apple are aware of the problem and are looking for a fix

Turingtest2's user tip Troubleshooting issues with iTunes for Windows updates includes the details of the operations needed to uninstall all components of iTunes, as well as a link to an alternative installer for the current version of iTunes (labeled - somewhat misleadingly - as being "for older video cards"). This may resolve some apparent incompatibilities between the standard (full 64-bit) version of iTunes 12.1.1.4 and some 64-bit Windows systems.
