Yesterday I downloaded the UniDAC trial version, installed under Delphi 11.0.  Created a program that consisted of a connection, provider, data source, and a dbgrid.  Got connected to my SQL Server and the grid populated with the results of the query.  Fantastic, took maybe 10 minutes!

This morning I fire up Delphi 11.0, open the project from yesterday, and get a message "Class TSQLServerUniProvider not found."   Close the project, inspect the component toolbar, and sure enough "UniDAC Providers" is missing.  Shut down Delphi, re-ran the Unidac28 installation program.  Went into Delphi to check the component toolbar, and both "UniDAC" and "UniDAC Providers" pages are present.  Open yesterday's project, but again get "Class TSQLServerUniProvider not found".

Am I doing something wrong, or is this a known issue with D11 or the UniDac installer?
