Installation oddity -- installer insists that PostgreSQL has failed to start, even though it is started and functioning correctly

Sorry about the HTML post, but I wanted to include the error form.

When trying to perform an upgrade with PostgreSQL 8.3.5 over 8.3.4, the
installer insists that PostgreSQL has failed to start.

However, I can see the processes in memory (it has indeed started) and
even attach with PG Admin III and perform queries.

PG Admin III confirms the version string as:

PostgreSQL 8.3.5, compiled by Visual C++ build 1400.

My machine has the following parameters:
