Description:
I created connection for my PHP project to MySQL from NetBeans. I am able to access my DB only from NetBeans after that, but not from my MySQL WorkBench.
I get this message:

Exception = System.AccessViolationException
Message = Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
FullText = System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

How to repeat:
Create connection from IDE (here NetBeans) to MySQL database.
Then open the MySQL workbench and open a connection to start querying

Please, check if the same problem still happens with a newer version of Workbench, 5.2.35.1.

I couldn't install the newer version. It says "installation ended prematurely"

Please find workbench_user_data.dat in C:\Documents and Settings\aravind\Application Data\MySQL\Workbench. The file might have been corrupted.
Solution is, rename the file to anything you want. Close the instance of Workbench and reopen it after a while and there you go.
(A new file workbench_user_data.dat will be created in the same location in addition to the one that you renamed.)
