Did you extract both main.zip and en-US.zip to the same folder to run (has been explained manymanymany times)?
No, I have only extracted the en-US.zip package. So I have to download and to extract both packages into the UUP folder?
Does anybody know what this 'updates for RS_PRELEASE_FLT_PREV 10.0.16232.1004' is all about? I have it installed before Build 16237.
I think it would be better if you just create ISO and upgrade manually . Its gonna take you 2 hours to install it if it finishes fine. Just download the decrypter , launch it , paste the path to the UUP files it needs (c:\windows\SoftwareDistribution\...), create ISO and you don't even need to create bootable usb. Just open the ISO , run setup->upgrade, leave all apps and files ->the end. It was the last time I waited 2 hours to update the windows... next time I will create ISO since the download only takes 2 minutes to complete and creating the ISO takes max 4 mins
That's the best option. I'm going to restart in safe mode. Copy all files, turn off wifi for avoid another download and convert the files.
It is a test Update to test staggered release on Windows Update instead of releasing Build to everyone at same time.
