Hi, all. I need help. I try to install Kayako on Server 2008 r2 x64. I installed the PHP, has configured the database MySQL. I created an application in IIS, and gave all super rights to the Kayako application folder and C:\php folder, copy Kayako application folder, put the key.php there too, but nothing works, not the root directory, not \setup. Error HTTP 500.0 - Internal Server Error What should I do?
