title: How to check for the msoledbsql driver installed in the system (in Delphi 5)
body: <p>My intention is to use the new Microsoft OLE DB Driver for SQL Server (msoledbsql) for database connection in Delphi 5 if it is installed in the system. If it is not installed than I am using old driver (sqloledb).
  My question is: What would be the proper way to check for the driver installed in the system?
  I guess it has somethink to do with Registry check and also some dlls existing in the folder. I know how to chek for dlls but I am not sure about the Registry.</p>
