[tex-live] Problem with new TeXlive 2012 pre-test install on Win32

[John Minter]

I have TL-2012-pretest running on a couple of systems without issues.
I went to do an install today on a winxp box and ran into a problem.
Given that you are about to burn DVDs, I thought I should report it

For reference, it is being installed to  TEXDIR: "C:/apps/texlive/2012"

Along about line 4900 of the log file, I start getting messages like

(c:/apps/texlive/2012/texmf/tex/generic/hyphen/dumyhyph.tex)
(c:/apps/texlive/2012/texmf/tex/generic/hyphen/zerohyph.tex)
! I can't find file `dehypht-x-2012-05-30.tex'.
<to be read again>
                   \relax
l.375   \repeat

(Press Enter to retry, or Control-Z to exit)
Please type another input file name:
! Emergency stop.
<to be read again>
                   \relax
l.375   \repeat

No pages of output

Then later (about line 5800) I get this error
Running: "C:\apps\texlive\2012\bin\win32\pdftex" --ini
--jobname=eplain --progname=eplain -translate-file=cp227.tcx
*eplain.ini <nul

The file eplain.fmt was not created due to some errors.
See the log file
C:/apps/texlive/2012/texmf-var/web2c/pdftex/eplain.log for details.

And when I do this, I find at line 66

! I can't find file `dehypht-x-2012-05-30.tex'.
<to be read again>

And then a message at the bottom saying no fmt was generated. Same
issue for several other format files...  The installation is totally
broken.

Any suggestions on how to fix this?

Best regards,
