I have been ask many question but never have response. T_T I follow the programmer's guide and use automatic tools to generate .MSI installer. for copying the dll to the server. i did that. and restart the server. when i browse the web, its a good think no error is prompted (like before i install the .MSI). but instead, now its loading forever. just like its loading something that is so big. i wait for 30min. yet nothing happen. what is the problem actually ? thank you, folks.
