Well bugger me, first I downloaded ver x86 then based on discussions here x64 of build 7068. Well NEITHER of them will install.
Not from a clean install or from an upgrade from a prior version.
So I'm back to installing 7000 followed by system upgrade to 7057 which is at least working reasonably well.
Not the end of the world but still annoying. The install starts well, gets through he initial expanding of files, reboots, does all the other stuff.
Just as it is about to finalise, the screen dumps to black, I get a cursor flash top left for an instant, the screen splats then nothing. Just sits there in black.
I'm thinking I might upgrade to 4gig of ram. I also think the nVidia GTX 9800+ is a piece of crap and may be the issue, just not sure.
I'd like to move to x64. Guess I'll have to wait for the next major release and pray it works.
