I installed MySQL GUI tools after installing XAMPP (Installer method under Windows XP). Trying to run MySQL Administrator there is a warning at the beginning about the configuration file that could not be found. After that the administrator installs, but with many tools grayed out.
I read several posts in MySQL forum (http://forums.mysql.com/read.php?34,128 ... msg-128259), but none solves the problem. I think there could be a problem with MySQL configuration file. If mysql is installed on Windows with its own mysql installer, not XAMPP, it is configured to read my.INI as the configuration file. XAMPP installation on windows configures MySQL to use my. CNF, as in LINUX.
Could it be that MySQL Administrator is configured in Windows to look for my.INI instead of my.CNF?
A minor problem when using CNF extensions in Windows is that this extensions are recognized by windows as 'Windows SpeedDial ' files, therefore, it cannot be associated, for example, with text editors.
