[Koha] Error 500

[Ata ur Rehman]

Dear All
Assalam O Alaikum

I am new user of Koha.  I just installed Koha on windows XP.  When i
open the browser with localhost in address bar, it redirects to
http://localhost/cgi-bin/koha/opac-main.pl and I find the error 500.
I looked into the error logs of apache.  That is:

[Tue Nov 14 17:43:39 2006] [error] [client 127.0.0.1] Premature end of
script headers: opac-main.pl
[Tue Nov 14 17:43:39 2006] [error] [client 127.0.0.1] Can't locate
HTML/Template.pm in @INC (@INC contains:

C:/usr/koha224/opac/cgi-bin/koha/opac-main.pl line 5.

Please suggest some solution.  Also some beginers tutorial if possible
