Migration Wizard Error: Library not registered

I am trying to migrate an Access database to PostgreSQL (behind our
firewall) using the Database Migration Wizard. I select "Access" as the
Database Type and enter the local path in the ".mdb File". After clicking
on "Next", I get the following message (lifted from the "pgAdmin II_xxx.log"
file) and the migration to the remote server fails.

File information: pgAdmin2.exe is verion 1.02; pgMigration.dll is version
1.02 and was successfully registered. This happened before and after the NT
workstation was rebooted. Any help would be appreciated.
