I am installing a VB6SP6 app on WinXP Pro connected to SQL Server Express 2005. I installed on (5) machines without a problem. On the next pc, I get the error: Run-time error 3706 Provider cannot be found. I installed and tested the SQL Native Client the same on all machines and received 'Test Completed Successfully' so am thinking the database connection is working but not the ADO database connection. Have searched Google & EE for this error message but mostly get dead-end links. I need help fixing this error.
