Thanks!
I downloaded and unzipped PHPMyAdmin. I try to run index.php but just Notepad opens. I guess there may be something wrong with my installation of MySQL.
I've got F:\PHP with directories dev, ext and some files like php.exe. I run it and see: "PHP Warning: PHP Startup: Unable to load dynamic library 'F:\php\ext\php_mcrypt.dll' - The specified module could not be found. in Unknown on line 0".
What can be the reason that there is no this file? Do I have to reinstall PHP? (I am not the one who installed this server and this PHP so I'd better not reinstall it. I'm not admin but just trainee in the company

).
I also have got F:\Program Files\PHP with one file php.ini.
Greetings!
