WampServer

I am frustrating this below error comes during drupal installation (wodpress is working fine). I also increased the max allowed packed and max execution time, but error comes. i have installed latest wamp 2.5 32 bit.

I tried to drupal old and new version also. whatever version it is error comes common.

the error comes after modules installation process.

Please solve my problem.
