So, what we're talking about is something like the way VB6 used to
handle add-in tools... only less structured.
You have my sympathy. :-)
If the file you are appending to really is unstructured text (as opposed
to something with an ini file structure, but with a txt extension), I
think you only have two choices:
1) Require the end user to modify the file themselves. (This is almost
certainly not an option... if for no other reason than it is seriously
unfriendly to less experienced users).
2) Create a custom operation. As you observed initially, this is an area
which is extremely susceptible to problems and should be approached with
caution. If I had to do this, I would code it as a custom action DLL in
C++, making sure of course that there are no external library
dependencies. The reason for choosing a DLL instead of an EXE is just
personal preference. I would probably also submit a support request to
the developer / publisher of the existing application asking them to use
a more structured format, ideally either ini file or XML, in subsequent
releases.
Good Luck!
Regards,
Richard

Yes, these are configuration files of another existing application (not
mine).
I must append my text to the text file in order to add this specific
feature (yes, the user can choose to add it or not)
