Installing PEAR

Hi,
I am pretty new to PHP development so bear with me if I ramble on.

I read about PEAR and I thought it would be a good idea to install it in my local machine.

I went to my PHP folder (located in C:\Program Files) but it did not have the go-pear.php script in it. I therefore downloaded go-pear.php from pear's website.


I downloaded to my htdocs folder as I thought it might be easier to load the file on my browser and follow the steps from there.

I did not change any of the configuration settings and hit next. This was the message I got:

Fatal error: require_once() [function.require]: Failed opening required 'PEAR.php' (include_path='C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\pear/temp/C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\pear\temp\gop8C1A.tmp' ) in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\pear\Archive\Tar.php on line 21

I checked the pear folder that was created. PEAR.php is located in the pear folder but not within the Archive folder. Should I modify Tar.php so that it grabs PEAR.php from the correct location? Is there any other solution to this?

Thanks
