The '%s %s' is VERY important, PHP will not work properly without it. 9) Now navigate to: HKEY_CLASSES_ROOT 10) On the edit menu select: New->Key 11) Name the key to the extension you setup in the previous section. e.g. ".php" 12) Highlight the new key and in the right side pane, double click the "default value" and enter phpfile 13) Now create another New->Key under HKEY_CLASSES_ROOT and name it phpfile 14) Highlight the new key phpfile and in the right side pane, double click the "default value" and enter PHP Script 15) Right click on the phpfile key and select New->Key, name it Shell 16) Right click on the Shell key and select New->Key, name it open 17) Right click on the open key and select New->Key, name it command 18) Highlight the new key command and in the right side pane, double click the "default value" and enter the path to php.exe, e.g. "c:\php4\php.exe -q %1" (don't forget the %1). 19) Exit Regedit 20) In Personal Web Manager, right click Home and select properties, give the execute right to that directory 21) Restart your computer ******************************************
