You get the error "Failed to open branch database (BWNOBBD)" when trying to initialise the product if ukbridge.tbl is missing. The Bank Wizard 1 to Bank Wizard 2 bridge (bwcore32.dll) and also the Bank Wizard 1 to Bank Wizard 3 bridge needs this file to operate.
Data Manager only downloads this file from the Online Update server, or copies it from the DTF CD, if your Bank Wizard 2 or Bank Wizard 3 licence key includes the Bridging Software option.
You can use Data Manager to check whether your licence has this option.
