Installation Errors - Blank Screen - Possible Path Issues

I have successfully installed Eventum on a Windows 2003
server running IIS,
php and mySql.

 

After installation I received a blank screen on index.php.
Using the list
advice I have enabled error reporting. I am receiving the
following errors:

 

Warning: main(/eventum/include/class.misc.php): failed to
open stream: No
such file or directory in
C:\Inetpub\wwwroot\efficinetonline\eventum\config.inc.p
hp on line 141

Warning: main(): Failed opening
'/eventum/include/class.misc.php' for
inclusion (include_path='.;/eventum/include/pear/') in
C:\Inetpub\wwwroot\efficinetonline\eventum\config.inc.p
hp on line 141

Fatal error: Undefined class name 'misc' in
C:\Inetpub\wwwroot\efficinetonline\eventum\config.inc.p
hp on line 156

 

Here is the variable settings in my config.inc.php file:

 

// definitions of path related variables

$app_path = '/eventum/';

if ((substr($app_path, -1) != '/') &&
(substr($app_path, -2) != '\\')) {

    $app_path .= '/';

}

define("APP_PATH", $app_path);

 

My windows path is
C:\Inetpub\wwwroot\efficinetonline\eventum\

 

Can anybody assist in telling me what I am doing wrong.  I
have tried
virtually every combination of path and cannot get it to
function.

 

I have changed the app path to
C:\Inetpub\wwwroot\efficinetonline\eventum/ 

I receive a "cannot connect to the database
error"

Any suggestions are appreciated.
