Actually, rethinking this, this are simple text files I need to *append*
text to them. (not XML or INI, just plain text files).
Roll back (uninstallation) would mean the text that was appended should be
stripped down, baring in mind other text might have added later on.
What do you think?

It depends what type of text file.
If the files are XML, the wixca.wixlib includes a custom action which may
accomplish what you need.
If the file is an older style .ini file, then there may be support for
what you need built into Microsoft Installer (see the IniFile element in the
WiX help).
If neither of these support what you need, I would suggest first coming
back to this mailing list with a more complete description of what you need
to do – it may be more sensible to do what is being asked of you a different
way to avoid problems with component rules etc. If necessary (and hopefully
it will not be), you will have to generate a custom operation – either in a
DLL (as a custom action) or as an EXE which is executed during installation.
I say that hopefully it will not be necessary because as you will know (if
you are a regular reader of this group) custom actions are notoriously
difficult to get 100% right when you take into account the repair and
rollback requirements… and if you get them wrong you may not know it until
it is too late to fix.

Hi,
My installer is supposed to perform a custom installation procedure, such
as parsing existing text files and inserting it's own text elements in these
files, and also appending text to existing text files.
Is there a mechasim for such actions? If not what should I use - an
external DLL seems risky.
Thanks
