Just to clarify: while VS IDE integration is not required, it doesn't hurt, and can't be a reason of any failure like discussed here.

The admin privileges request is most suspicious. I would blame it for everything, e.g. I could suspect that there is a problem that admin process working with other environment variables could simply be unable to find the symbols.

There must not be an admin request. It needs clarification, if you use different users to run VS, and run LO.

Of course, attaching to a running process doesn't need F5 until a breakpoint hit, or otherwise paused; when in pause, F5 would resume (and F10 would step over).

Good, at this point you should have debug symbols.

To be clear, this is for the IDE integration, debugging doesn't need
that, it would be for tab completion while editing code, etc.

If you just want to debug, you can simply open the file in question and
put breakpoints there, no need for any kind of projects.

I don't recall I had to have admin privileges to debug a normal
soffice.bin process, but otherwise yes, that's how you do it, yes.

Not sure you need this step, possibly once you attach the debugger to
the process, it'll wait for your breakpoint to be hit, so you don't have
to start anything.
