I have just installed BOXI 3.1 SP5 in my LIVE environment and it is missing Network layers. I have checked the Connection Server and there are several missing Network Layer databases, Sybase and Excel to name a few.
This means that I can not go into Designer and create Sybase or Excel connections that are required to run reports.
As per previous SAP notes etc... I have checked my Environment variables and everything seems in order and I have checked that all the relevant files are present in C:\Program Files (x86)\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer.
This is an urgent matter as it is my LIVE environment... all worked perfectly in TEST.
