I am out of the office, but from memory and looking at the start of this thread I have the version that ended 228 x64. I would have expected to be updated to any version release after that, but now I think it should 11.3.x.x.x.
It would be great if you could send us your latest FlashInstall.log. This would help us identify where this is still failing. This still appears to be a connection problem, maybe to the installers this time.
I had to reboot this morning and on reboot Flash opened to say an upgrade we available. I declined. You can get the logs from the link below. I have included 32 and 64 bit. I renamed them so you know which is which.
This seems to be due to the fact that the release of 11.3 was a scheduled release. For scheduled releases, the current Adobe policy intends to notify users of the update for a period of time (currently 30 days) before updating automatically.
