Warning!!! can not get write access to config

Hi All...

I'm new to Dolphin and trying to install it in my Windows Xp Professional (with IIS) machine. After I overcame initial glitches, I'm stuck in Cron Jobs!. It's giving warning message at two places:

Warning!!! can not get write access to config file ../inc/header.inc.php. Here is config file

The second warning is as follows:

Warning!!! can not get write access to config file ../periodic/periodic.file. Here is config file

MAILTO=mirajs@gmail.com
0 0 * * *  c:\php\ -q C:/Inetpub/wwwroot/php/periodic/cmd.php
*/10 * * * *  c:\php\ -q C:/Inetpub/wwwroot/php/periodic/notifies.php
*/10 * * * *  c:\php\ -q C:/Inetpub/wwwroot/php/periodic/tags.php

I really don't understand how to overcome the problem. I searched and saw some remedies adviced in Linux machines (changing the chmod etc.) but I couldn't find any for Windows.

I even tried ignoring it and going to the next step, but finally I end up as Dolphine still not properly installed. (I have php and mysql properly installed and even got Imagemagick installed properly).

Please help!!! Else I can't use this great software at all.

I'd be thankful

Thanks
