Hello guys, yesterday i installed Wampserver 2.0 since i had problems to run NuSphereS4 with Tech Platform and i need the Apache server.

Here is the situation:

I have my project files at: C:\Program Files\nusphere\phped\Projects\EO\

So i did the mapping for the project:
Run Mode: 3rd Party WEB Server
Root URL: http://localhost/Program%20Files/nusphere/phped/Projects/EO/
Remote root directory: C:\Program Files\nusphere\phped\Projects\EO\

The Apache runs through the port 80 (which is not used - confirmed by the Wampserver). When i press Run to run my project (displayed by Firefox) it returns:

"Not Found

The requested URL /Program Files/nusphere/phped/Projects/EO/index.php was not found on this server."

The debugger won't start at all.

Could anyone help me please?

Are you SURE, that you have localhost mapped to C:\ ??? otherwise......seems like a misconfiguration to me.
The Root URL: should reflect a directory under your webserver's root, typically "http://localhost" points to "C:\Apache2\htdocs" for Apache assuming "C:\Apache2\" is Apache's installation directory.
Then if you want to run your project on localhost, you need to have the project under this webserver's root directory, i.e.
Remote root directory: is "C:\Apache2\htdocs\myproject" (assuming conditions above) and then you can have
Root URL: set as "http://localhost/myproject".

P.S. It is also possible to create own hosts like "http://myproject.local", but it needs editing of Apache's advanced configuration and 'hosts' file (if you do not know what is it, stick with "localhost").

Thank you very much for your help. I will do the suggested, i guess i didn't get the configuration right.
