How to Reconfigure the UserDSN (database registration) for the Contact Wolf Database CWdb240.mdb
The UserDSN on your computer determines the path to the Contact Wolf database fileCWdb240.mdb

A UserDSN is required or Contact Wolf will not be able to find the database.

The Contact Wolf database file name is CWdb240.mdb  It can be in any folder you choose as long as the folder location is accessible and has read/write privilages granted for your user account. You will normally need admin rights to change the UserDSN on your computer.

When Contact Wolf is installed on a computer it installs the database CWdb240.mdb to the following folder location depending on the Operating System being used:

NOTE: The database location was changed with version 2.40 and later to comply with Microsoft Developer Requirements:

NOTE: Sometimes users have installed different versions and may have several CWdb240.mdb data files in different locations. We recommend checking all possible folder locations below and searching your computer for file name CWdb240.mdb
