WampServer

Hi, I installed wamp5_1.4.4 and athe add-on PHP4.4.2a_add-on but there is no new entry in the wamp tray icon menu to switch wamp to php4 mode . The menu is the same as before as shown on www.wampserver.com . I can see there are new folders added (I compare with other compuer where I did not install the add-on) php4 and scripts which has the page switch.php but how can I switch to php4 mode ?
