everything is working alright, except q2s script. i have tested q2s script on both wamp and vertrigo but couldnt run with same errors. i search on internet errors "Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error". they said script require  zlib

When i turn on  zlib , i can enter http://localhost:82/q2s/ but some errors  still display

OK, I understand the problem. It's a bug in 1.5 beta, where the QA_DEBUG_PERFORMANCE constant is referred to before it is defined. For now you can just fix this by editing qa-include/qa-index.php to replace QA_DEBUG_PERFORMANCE with false (unless you do, in fact, want to debug performance).

OK, for this it looks like you should switch off QA_HTML_COMPRESSION in qa-config.php.
