The custom installer for iTunes 220.127.116.11 is ready to download. Apple added more bloat to the new 12.6 builds, the size difference is about 50 mb. I don’t know what they added and to be honest, I don’t have much time to dig deeper into the installation to discover what they did.
Notes: the Old Video Cards installer has been discontinued but I’ll keep the latest custom version available in the downloads page as a resource for those that may still need it.
For the original installer links and troubleshooting on Windows, you can read this support thread at Apple forums.Downloads
