install_driver(mysql) failed

[Frederick Eason]

Please help!

I have DBD::mysql installed, and all the files are in the right places, but when I run the program, I receive this error:

install_driver(mysql) failed: Can't load 'C:/wamp/bin/perl/site/lib/auto/DBD/mysql/mysql.dll' for module DBD::mysql: load_file:The specified module could not be found at C:/wamp/bin/perl/lib/DynaLoader.pm line 191, <FILE> line 3.
at (eval 401) line 3.
Compilation failed in require at (eval 401) line 3, <FILE> line 3.
Perhaps a required shared library or dll isn't installed where expected
at C:/wamp/www/wakaba.pl line 45.

What's wrong with the program?

I've using WampServer 2.2 64-bit with Apache 2.4.2 and ActivePerl 5.16.0.
