What could be done, I think, should be to download the comp-
lete MiKTeX package,  and launch the installation after the
Lilypond setup is done. Of course, Jan's solution seems mor-
e plausible if those "tarballs" are really a lot less heavy
than the full 25 Mb MiKTeX 2.0 package. It's obvious why so-
mebody using a modem line, and wanting only to use Lilypond
would prefer such a solution. If really that's a problem, w-
hy can't an additional package, that installs every other c-
omponent of MiKTeX that wasn't installed during the Lilypon-
d setup be provided?

The first solution that comes to (my) mind, would be to hav-
e the bash installation script generate an exported registr-
y value file (the *.reg managed by Regedit) and have it ins-
ert all needed values for Python into the registry. It does-
n't require much work. I attached a file that should set ev-
ery key necessary to Python, but I haven't any way of testi-
ng it.  I'll explain what the paths are, though I doubt you
need help.

I installed Python in the following path :
C:\Program Files\Musique\Lilypond\Python\

All the keys that follow the [HKEY_CLASSES_ROOT\.py] comman-
d are relative to the file extensions management, and aren'-
t really required though very practical for Windows (and fu-
rther uses of Python, non-Lilypond-wise). In fact, this sho-
uld act as a sort of environnemental path variable setting,
at the exact same title as the old SET PATH function,  just
specificly for Windows. There are no other means to erase t-
he keys for deinstallation than regtool. The following keys
must be deleted :


I hope this information is of help, though I doubt it's wha-
t you needed.

If Python is acting up because of unproper register setting-
s, I'm afraid that's an obligation.
