egroupware 설치과정에 대해서...ㅠㅠ

egroupware를 설치하는데 여간 힘든게 아니네요

xp에 아파치2와 php5 그리 mysql를 사용해서 하는데
거의 설치를 완성했습니다.
근데 로긴만 하면 페이지를 표시할수 없다고 나오네요...
로긴 암호를 틀리게 적은것도 아니고(틀리게 적으면 틀렸다고 표시되요..
모든게 완성 된거 같은데 왜 왜 왜 로긴만 하면 페이지를 표시할수 없다고 할까요... 500 - 내부서버오류라고

구글에서 외국 사이트찾아서 검색도 해보고 겨우겨우 여기까지 설치했는데. 정말 난감하네여..
http://localhost/egroupware/setup/ 이라 주소창에 치면 egroupware에 관한 카테고리들이 다 나오고
check_install.php 도 잘 되고

pear 설정탓 땜인거같기도한데 설정을 어떻게 해야할지 모르겠네요
그다음 로긴만 하면 ㅎㄷㄷ
Header Admin Login은 잘 되는데 Setup/Config Admin Login 이 로그인 만하면
http://localhost/egroupware/setup/index.php 이렇게 넘어가는데 거기서 페이지를 못찾네요

php도 안해봐서 이번에 설치할때 php.ini 란 소스도 조금 손봤고,
뭘 어떻게 건드려봐야 하는지 감을 못잡겠어요.
거의 다 설치 됐는데 왜 이런일이...

혹시나 이 그룹웨어 설치하신 분 계시면 좀 도와주세요....
