Failed to open stream: Permission denied

Hi All,

I am trying to build an application. I went through the phprunner wizard and built the application as a new project and copied the files into a director in my web server. However, when I tested the application on the browser it threw an error type 2 as follows:
Error description fopen(D:\Web Sites\erim\erimR\templates_c\wrt4a0b024273b44) [function.fopen]: failed to open stream: Permission denied

URL xxxxxx.xxxxxxx.xxxx.xxxx/login.php?

Error file D:\Web Sites\xxxxx\xxxxx\libs\internals\core.write_file.php

Error line 32

SQL query
I am not sure why. Could somebody help me please.
