I've just banged my head against the wall with the RT7 process that quits after an hour with a error message that people say needs to be adressed with a windows reinstall or some such nonsense.
Right now I'd really like to find another way of making a winsxs less win7-64 installation-
If you have issues with RT7lite, you can use the presets in this thread. Thats what enabled me to finally get a working RT7lite install.
I could never the vLite to play nice with RT7lited iso though. Dunno how it worked for the other guys, as I followed their steps exactly and vLite always craps out on me
