PHP on Win XP 64 bit and IIS

["Simon michnowicz" <simon.michnowicz@xxxxxxxxx>]

I installed PHP version 5.2.1 on XP  64 bit version (using IIS CGI), and 
although it installed without error, I get an error
whenever I access any 
php script, "The specified CGI application misbehaved 
by not returning a 
complete set of HTTP headers.".
I tried both manual and automatic install 
techniques.

The same installation on a 32bit XP version worked without a 
problem.

Can anyone tell me if PHP works on a 64 bit machine with IIS? If 
so, what do 
I need to do to make it work?

Much thanks
