Delphi 2009, latest driver build, MSSQL 2008.
Drop a TSQLConnection on a form, select Devart SQL Server, connect to master database. Run the application. When I close the app, I get several exceptions like this:
---------------------------
Debugger Exception Notification
---------------------------
Project Project9.exe raised exception class EOleSysError with message 'Classe não registrada, ClassID: {89F49E65-F6E0-11D6-9038-00C02631BDC7}'.

I can not reproduce the problem.
Please, try to connect to SQL Server using DbxSda Demo and check if the problem persists.

Same problem with DbxSda Query Demo.

I've tested on a second machine and the problem is the same. You have to run the app inside the IDE in debug mode.

This problem is connected with OLEDB but not with DbxSda. Please try to clean the registry on your machine (using, for example, the Ccleaner application).

I did use the CCleaner and the registry is clean, but the problem is still happening.

I still can not reproduce the problem. Please try to compose a small sample to demonstrate the problem and send it to dmitryg*devart*com.

I already told you that the problem is reproduced in your Query demo that ships with the driver.
One detail I forgot to tell is that I'm using Windows Authentication and not SQL Server authentication.
I've also recorded a small video showing the problem in your Query demo. I've sent this video to your email.

Thank you for information. We have reproduced this problem and fixed it. This fix will be included in the next DbxSda build.

We are planning to release the new build of DbxSda in the end of the following week.
This is not a critical problem, because it appears only when you run the application inside the IDE in the debug mode. But if you need the new build as soon as possible, we will send you a custom build with the fix. Please contact us by dmitryg*devart*com email and specify your developer license number.
