Hi Lauro,

I have just recreated a new installation of PostgreSQL here using the 8.1.3
installer and the PostGIS 1.1.1 installer from http://www.webbased.co.uk and
it worked without any problems here on a WinXP SP2 machine.

First thing to check would be that the C:\Program
Files\PostgreSQL\8.1\lib\liblwgeom.dll file actually exists on your
computer; if you can see this file then it might be a permissions problem as
the user the PostgreSQL server runs under (normally postgres) must be able
to read this file.

Also, if you tick the "Create Database" option on the PostGIS 1.1.1
installer, can you connect to the default "dcmms" database which is created
by the installer using psql, e.g. psql -d dcmms -U postgres?


Kind regards,

Mark.
