CGI errors on startup

[gpcc]

Am running windows 2k3 server with IIs v6, have installed php via auto installer and appeared to work ok (not sure of php).
Downloaded Snippet auto Installer and tried to run via browser in web server. I am getting these errors:
"CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers."
Appear all php files giving me this , does php need to be set up for CGI?
thanks for help

First, let's try and figure out if PHP is running on your server.

Can you run this file here:

http://www.yourdomain.com/snippetmaster/includes/diag/phpinfo.php

This should display all the PHP configuration settings for your web server.  If it shows anything else, please let me know.

Thanks.

Problem seemed to be with an old copy of PHP(v5.0) still registered. Deleted this and reinstalled PHP V5.1 and it now my php works.
ran phpinfo and get all settings now.
However now when I run SnippetMaster autoinstaller it slowly executes (blue line in IE) then gives a blank page and nothing else.

Hmm... Sounds like it still might be a php problem.  Feel free to send me your FTP user details and I can try to install it for you.

Yes was PHP still, apparantly the old version installed an .ini file in the PHP folder and the new version installed the new .ini in c:\windows, thus php worked ok because it new where it was, however Snippet thought it was in PHP folder and was trying to use that one which was causing the errors. Pointed Snippet to C:\windows and Snippet works fine and am editing it now,
Thanks for help.
