System Service Exception after upgrading to WIP 17686

Hello, 

When I Tried to install 17686, I got to 44% on the 1st reboot and then GSOD after the reboot. I then tried a Clean Install from my UUP to ISO file and both times it failed to install. I then tried to download the Wincentral link 64-bit and was able to download 2.5 Gb. of the 4.07 Gb. When I tried to restart the download process, I got this message: https://cloclo38.cldmail.ru/2kHZ4gRBNEbxWLY7zJMb/G/48S7/EjBhnz7tq/17686.1003.180603-1447.RS_PRERELEASE_CLIENTCOMBINED_UUP_X64FRE_EN-US.ISO?key=065643dd5e63101f2ff19646f4a98b485c532bc1&key=065643dd5e63101f2ff19646f4a98b485c532bc1. I tried to install WIP 17692. It got to 77% and rebooted. I had read somewhere that I need WIP 17686 installed to install WIP 17692. Where can I download a Workable Copy of WIP 17686?
