TYPO3 Core

When I unzip the dummy-3.6.0RC2-2.zip file to:

C:\apache\Apache2\htdocs\typo36\dummy-3.6.0RC2\
and then access it on:
localhost/typo36/dummy-3.6.0RC2

I get the following message:
"Cannot find configuration. This file is probably executed from the wrong location."

After doing some google I found this solution to that:
http://typo3.org/1422+M54defb70332.0.html

I only needed to solve this part from that message:

"
Thanks for the clue. The fix suggested in the archive did not work for me,
but in a similiar vein I hardcoded a path in index.php (line 51) from:

define("PATH_thisScript",str_replace('//','/', str_replace('\\','/',
php_sapi_name()=="cgi"||php_sapi_name()=="isapi" ?
$HTTP_SERVER_VARS["PATH_TRANSLATED"]:$HTTP_SERVER_VARS["SCRIPT_FILENAME"])))
;

To:-

define("PATH_thisScript",str_replace('//','/', str_replace('\\','/',
$HTTP_SERVER_VARS["SCRIPT_FILENAME"])));
This solves the problem, and the site now loads.
"

But even then I fail to install typo 3.6 RC2.

The error message I get after that is the one that I have uploaded with this message.

Please note that I am using the newest stable php version arround so it would be odd to make this version gold.
