When trying to create a New Server Instance, at the 3º window of the Wizard (the Test to DB Connection), the connect is great, but when I click NEXT, the error-window pops-up:


(My poor translate: Reading or writing in protected memory try. Generally, this is a indication that the other memory is damaged.)

We are sorry for the inconvenience but an unexpected exception has been raised by one of the MySQL Workbench modules. In order to fix this issue we would kindly ask you to file a bug report. You can do that by pressing the [Report Bug] button below. 

Please make sure to include a detailed description of your actions that lead to this problem.

Thanks a lot for taking the time to help us improve MySQL Workbench!

UPDATE: I tried to open the program with the Admin. The problem is the same.

Thank you for the bug report. Could you please provide the output of Help->System Info. Are you trying to connect remote or local?. Thanks in advance.

I'm using it in local, with XAMPP. I don't have a remote database, so I couldn't test it remote.

I'm glad to help a so good program like this, even if my english is soooo poor :D

Do you have a Windows service defined for your MySQL server from xampp?
[1 Feb 2011 21:44] Andre Santos
Valeriy Kravchuk, sorry, I'm new to this, I don't know how I discover it. I just used the typical installation of XAMPP, and I turn it on usin' the XAMPP Control Panel. Even the root password I didn't change (its empty, by default)...
[2 Feb 2011 4:16] Valeriy Kravchuk
Let's say this is a duplicate of bug #59578. Most people had noted this problem with default xampp installation.
