PHP4 Refuses to Run in Any Directory Except c:\PHP4

I followed the install directions for php4 exactly but a simple phpinfo page wouldn't work. So I extracted all the files to c:\php instead and changed the paths accordingly, then it worked. So I started to change all the directory references back and I can change them all except for this line: Action application/x-httpd-php /php4/php.exe If I change it to Action application/x-httpd-php /dir/dir/dir/php.exe it gives me a type 400 error. I know that is the correct path however. Anybody else had this problem?
