Webpagetest Private Instance in XP SP3

Hello,

Has any one configured Webpagetest Private Instance in XP SP3.

I followed the steps given in Andy Davies Blog
http://andydavies.me/blog/2012/09/18/how…-instance/

I am getting error while starting Apache (Error screen attached)

I followed the same steps that i had done for Windows 7 and its working fine in Win 7

Please Help !

I run it in XP SP3 all the time as part of my dev environment. I usually use WAMP to set up the Apache and PHP install because it usually “just works” - http://www.wampserver.com/en/

The issue got resolved.
The XP that i was using was fresh, nothing was installed in ti.
I just did a windows update which installed .net framework and other components
because of which i did not got any error while running Apache

It working fine now.

Can you also send me a reference on how to add additional browsers like Safari, and others ?
