I download and installed the trial.
I have sp2 and .net Framework 1.1
The splash screen appears then disappears.
I am running MYDAC 3.5 for Delphi 6 trial successfully.
What am I missing?
The problem is that you do not have Html Help 2 engine installed. In a day or two we'll release new build with support of chm based help. Html Help 2 engine is included in MSDN and .NET Framework SDK.
