How to activate php_mailparse.dll in xampp server

Question

Hi, I am using xampp in windows. My 1.7.3 xampp server does not have php_mailparse.dll in php.ini. I tried to install it in all possible way but it gives module error.

Now I have taken xampp 1.6.4 it does have php_mailparse.dll extension in php.ini file. I have configured it like below -

extension=php_mbstring.dll

extension=php_mailparse.dll

extension=php_exif.dll

extension=php_mcrypt.dll

in php.ini config file. I have restarted my apache system with no luck. It showing error yet If i use any mailparse function.

I am stuck here. Could you help me to get rid of this situation ???
