Record(s) cannot be read; no read permission on

Trying to access data in an Access DB, I kept getting the error above..

A bunch of good sites provide the required connection strings, but in order to get it working I had to specify the FULL path to the System.mdw, i.e.

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=[full path to DB];Mode=Read;Jet OLEDB:System database=[full path to mdw file]
