I send you an email earlier, but i was wrong a bit. I thought we do not have any requirements listed for CS at all... What you just paste above is not the full text on the purchase page. I just went to that page to be sure, and the full text is this.
What are the requirements?
BlogSolution and ContentSolution are server-based applications. You need to install the scripts on your server. You need at least one domain and a hosting account that support:
*nix (Linux, FreeBSD, ...) box (we had no success installing BS on windows boxes..)
PHP
MySQL
Zend Optimizer
Additional settings may be required to use BlogSolution and ContentSolution with advanced features.
CS and BS are 2 separated programs, but we do say that both need same thing. Even if we mention that we could not install BS on windows, it does not mean that we installed CS, it means we never tried, nobody tried or reported it so we are not sure. The requirements for the scripts to work 100% should be clear enough, they say CS and BS need that stuff. Anything else may work, but we can't guarantee.
