Description:
When installer tries to remove the data files and they happen to be in use (because of an err on server removal so that service is still running or a data file is opened/locked by some other app)
installer runs into an exception and displays windwos AV dialog:
See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
How to repeat:
- uninstall server package using installer
- select "remove server data files"
- block one of the log files (e.g. Application Data\MySQL\MySQL Server 5.5\data\ib_logfile0) by opening it with a app that locks the file during use
- click "finish" button in installer and click "OK" on the following two confirmation dialogs
after the second confirmation dialog is confirmed, the err pops up
Suggested fix:
don't make it display an AV but rather a graceful "cannot delete file xy because its in use by another process" or sth alike.
