SDAC Error: [DBNETLIB][ConnectionOpen (InvalidInsance())]

Hi,

I have deployed my Delphi Application which is using SDAC VLC Components to another PC. There the TMSConnection.Connect ends up with the following Error:

[DBNETLIB][ConnectionOpen (InvalidInsance())]

Did I miss anything to install on the client?

Best regards,
Jörg

Please try to install the SQL Server Native Client provider and check if the problem still exists.

Thanks, problem is solved.

Is there any way to get it working just with standard MDAC 2.8?

This problem is connected with OLEDB but not with SDAC.
Maybe this topic will help you to solve the problem: http://social.msdn.microsoft.com/forums ... 058010f57/
