Initial screen of the debugger wizard.

Click continue.

Select the php to use in Installations found on your system field, this should be the one which has Xdebug.

Again for Setup this installation you should have the same value as the other selected field in this dialog.

Click the Continue button. Now in the next screen the INI file to be copied should be from a path below where the selected php executable is, while the Put debug version of ini at should be set to a directory somewhere below your home directory.

Click the Continue button. The next screen asks us where our extensions directory is. The path here should be the same path as that specified in the previous screen under the Put debug version of ini at field.
