Error Loading mcrypt.dll on Windows XP system

Hello, My setup: Windows XP Professional php-4.3.0-Win32 Apache_2.0.43-win32-x86-no_ssl In the directory c:\php-4.3.0-Win32\extensions, I have the file php_mcrypt.dll. The php.ini file, located in the c:\Windows directory, I have configured the following: ; Directory in which the loadable extensions (modules) reside. extension_dir = c:\php-4.3.0-Win32\extensions\ and ;Windows Extensions ;Note that MySQL and ODBC support is now built in, so no dll is needed for it. ; ;extension=php_bz2.dll ;extension=php_cpdf.dll ;extension=php_crack.dll ;extension=php_curl.dll a lot more..... extension=php_mcrypt.dll etc... My problem is that I cannot get Apache to properly load the mcrypt module, I keep getting the warning message: Unknown(): Unable to load dynamic library 'c:\php-4.3.0-Win32\extensions\php_mcrypt.dll' - The specific module could not be found. Does anyone know what I am missing or if there is a workaround to this issue. Any help would be appreciated. I am kind of new at this. Thank You, Jim
