the application failed to start because a needed componet is missing

[c dot n dot wilson at att dot net]

Hello i have looked through the message boards but did not notice a specific answer to my problem so here goes]

when installing xfree everything went fine i did not notice any error messages and nothing seemed to have gone wrong well when i enter the XWin.exe -screen 0 800x600x16
command  it says command not found ( yes im in the right dir) so then i tried to open the startxwin.bat from a command console and this is the error i get from a pop up error message (nothing wrote to the console)

 " The application failed to start because a needed componet was not found. Re-installing the application may fix this problem" 

so then i started up cygwin again and gave this command
cd /usr/X11R6/bin then the dir command XWin.exe does not even list the output but when i look in the folder with windows explorer it is in there i can see it but it does not say its there  when i give the dir command and xwindows will not intialize so what do i do now ??
