Re: delphi11.3 Error as EOleSysError with message

没有注册类 is not a very clear error message to me...
What does it mean?
Did you try with another library?

Re: delphi11.3 Error as EOleSysError with message

My guess using Google Translate is that the error message means "no class registered".

So perhaps you don't have the proper OleDB provider installed for the Win32 or Win64 context of your executable.
