When trying to export any report (simple or free form) to PDF or HTML we receive the message "An internal error has occurred".

The error may be caused by the system failing to make a call to the relevant export library. This can be fixed by the following commands on the BSI server(s):
cd %OG_HOME%\bin
regfiles.bat 3
The OS finds them again from the updated registry information.
