Description

How can the error "Unknown Error 0x800A0E7A Provider cannot be found" be rectified? This happens if trying to start any connection, using CA Repository Engine, with e.g. Oracle, MS SQL Server, or Sybase as the repository's database.

Solution

Most likely, the file sqlOledb.dll is not have been properly registered. You need to register this file with regsvr32. Then try to connect in the CA Repository Engine again.
