WampServer

I get the following error messages when I start Wampserver 2:

1. Php-win.exe faild to start because php_pdo.dll was not found.
2. The application failed to start because php_pdo.dll was not found.
3 The application failed to start because libatk-1.0-0.dll was not found.
4. The proceedure entry point zend_unmangel_property_name_ex could not be located in dll.

After each error message it suggests reinstalling might fix the problem. I have done so to not effect.

Wamp server actually loads and works ok. These messages also occur if I alter the php settings or add/subtract a php extension.

Any suggestions how I can fix this.

Have you unistalled it, then went to where it is installed and deleted the folder manually?

then reboot

download it again just incase, install see if that helps
