Looks like the documentation is not included - you may already be aware.
An error has occured:
Unable to open requested HTML document: .../share/pgadmin3/docs/en_US/pg/sql-vacuum.html
The standard postgresql documentation isn't included in the win32 package. You can download it and copy it to that location or configure the options to a different location (file or http) where the doc is.
