i have installed wamp on my computer running win server 2003 with iis. i even changed the listening port of wamp to 8080 so that it wont conflict with IIS but still when i try to run wamp i get the following error popup: php-win.exe-Application Error the instruction at "0x100e4e3d" referenced memory at "0x00080162". The Memory could not be "read". What should i do. i am a newbie trying to work with php!!
