NI: Notes.ini does not contain an entry for the Domino program directory (4315351)

Issue

Error reported during a BTCal / FB upgrade on Domino:

Notes.ini does not contain an entry for the Domino program directory

Solution

The notes.ini should be encoded with UTF-8. The easiest way to do this is to open the file in notepad, select Save As and then select the encoding as UTF-8. The below is an extract from the Comprehensive User Guide: Characters with diacritics (é, ü, etc.) are supported, but NOTES.INI must be in UTF-8 format (as it is by default). After making this change please restart Domino on the Domino Coexistence Server.
