Re: How to run multiple instances of Writer simultaneously?

You are using confusing terminology. "Spawn" is usually used in a software
context to mean starting a new process running another program, what is on
POSIX systems done using the fork() and exec() family of system calls, and
on Windows using CreateProcess(). On the other hand, "Writer" is not a
program by itself but (as you say) just one kind of document window that
the real LibreOffice process (soffice.bin) displays, and a single
soffice.bin process can have any number of Writer, Calc, Impress etc
document windows open simultaneously.

I.e., are you asking how to spawn multiple soffice.bin processes, or how to
open multiple Writer documents, at the same time?

For the first case, you need to spawn the processes with separate "user
installation" directories. For the second case, that should be what
normally happens.
