Just installed mydac11.exe which I believe is the correct version for Delphi 2007.
Installation completes with no problems.  I then add the TMyConnection component to a test program and get this error when I compile:
[DCC Error] Main.pas(7): F2051 Unit MemDS was compiled with a different version of DB.TUpdateStatus.
When I installed Delphi 2007 I did not include the DB components.  Is this the reason for the error, or did I install the wrong version of mydac?

Re: Delphi 2007 'compiled with different version'
MyDAC uses standard Delphi classes, in particular - the ones included into the DB module. Therefore, to use MyDAC, you should re-install Delphi using DB.
