[Typo3-windows] Install Problem

[Jimmy Coleman]

Hello,
I'm totally new to Typo3 but I have installed it succesfully on Mac OS X
with little problem. I am now trying to install the testsite package on my
Windows Server and am getting a series of errors. I'll document them as
clearly as possible, apologies if this seems a little long-winded.

1. When i go to the typo3/testsite/ directory to kick off the install
process, i get a "Cannot find configuration. This file is probably executed
from the wrong location."

I found a thread on the install list archives that had some advice for this
problem and followed it to edit the inti.php file in the typo3 directory -
commented out the first define ("PATH_thisScript.. line and uncommented the
second. and then ran the /typo3/testsite/typo3/install/ path directly, this
throws out an error:
In the main source distribution of Typo3, the install script is disabled by
a die() function call.
Open the file typo3/install/index.php and remove/out-comment the line that
outputs this message!

so i did that and ran the install script again and i get this!

PHP Warning:

calconf.php' (include_path='.;c:\php4\pear') in
C:\Inetpub\wwwroot\typo3\testsite-3.5.0\typo3\t3lib\config_default.php on
line 233

I'm not sure where it's getting the c:\php4\pear include path from! i can't
find it in the typo3 source so can only assume that it's part of my IIS or
PHP install or something?

Any help on this would be great, I've re-downlaoded the package and gone
through the steps above and got the same error's twice, so it's not a
download problem.

I'm a little rusty on PHP - so i could be making the mistake somewhere :(

Thanks,
Jimmy Coleman
