Installation problems with 'latex geometry.ins' and format file

[Alistair Matthew]

I have now downloaded and installed the latest Windows version of lilypond
from the NT/95 pages. I.E 1.3.46

Following the instruction there I need to download and unzip the geometry
package. I have done this. When I run

'Latex Geometry.ins' I see various messages flash past from latex then

INITEXMF: tex.exe failed on latex
I can't find the default format file!

If I carry on and run thru the angels demo stuff I get the same error
message plus some extra lines from the ly2dvi script

INITEXMF: tex.exe failed on latex
I can't find the default format file!
Traceback (innermost last):
  File "C:\lilypond\bin\ly2dvi.py", line 1170, in ?
    main()
  File "C:\lilypond\bin\ly2dvi.py", line 1131, in main
    outfile.end()
  File "C:\lilypond\bin\ly2dvi.py", line 361, in end
    os.rename(this.__tmpbase + '.dvi', outfile)
OSError: [Errno 2] No such file or directory

The Midi file is created, but no dvi. I think the error must be in the way I
have installed latex - but I can not see where. I have gone back thru the
archives of this list and can not find the exact situation I am in
described.

If I do a 'tex angels.tex' command after the script fails I get a dvi file
with the music displayed, but no other details, so tex seems to be working.

Does anyone know which file latex is referring to when it talks about the
'default format file' Also can anyone tell me where to look for the
latex.log file referred to. I can't find it anywhere and there may be
something in it that may help me track this down.

Thanks in advance if anyone can shed some light of this.
