Hello!

I'm using Delphi 2006 and MyDac 4.3. Embedded demo app tells me error on opening table (LOG-last line):

Any sugestions?

Are you sure you are using the "Share" folder corresponding to the libmysqld.dll version?
If this does not solve the problem try to use another version of MySQL Embedded server, like 4.1.18 or 5.1.22.
