I have a Virtual XP setup for running a few legacy programs which won't
run on W7-64bit. It's on a laptop running W7-PRO 64.

It's been ok for several years, but today it won't start. It puts up the
usual little window saying "Starting Virtual Machine" and the progress
marker starts moving to the right and when it's got about one third of
the way across after about 40 seconds, the window closes - and that's
that. No error messages or anything. At the point when it closes, I
would expect it to say "Starting integration functions" - or something
like that - but it doesn't.

I've re-booted numerous times to no avail. Malwarebytes doesn't find
anything amiss.

Anyone got any suggestions what to try next?

Go into Windows Update and see if you have KB2830477 installed.

If you have, remove it. And try VPC again.
