Problem with the installation page

[Manolito]

I'm trying to install OSCommerce 2.2 to the localhost server (my C: drive), but I can't start the installation from my browser (http://localhost/catalog/install/index.php). I only get this error message:

Warning: main(includes/functions/general.php) [function.main]: failed to open stream: No such file or directory in C:\wwwroot\catalog\install\includes\application.php on line 22

Fatal error: main() [function.require]: Failed opening required 'includes/functions/general.php' (include_path='.;C:\php5\pear') in C:\wwwroot\catalog\install\includes\application.php on line 22

I have PHP Version 5.0.2 and MySQL 4.0.22 installed. I read somewhere that OScommerce 2.2 aren't fully compitable with PHP 5, could that be the problem? What should I do? I'm new to this (no suprise) so don't be too technical...

Now I know what the problem were. My version (got it with a magazine) I installed weren't complete, a few files were missing.
