Can you tell me which IIS are you using to develop ASP Nuke? I use IIS 6 with SharePoint Services on Windows Server 2003. I noticed this error when trying to load setup1.asp
"Active Server Pages error 'ASP 0131'
Percorso principale non consentito
/setup/setup1.asp, line 1
Impossibile utilizzare il simbolo ".." per indicare la directory principale nel file di inclusione."
This means that you're using the deprecated "../" syntax to navigate into parent directories. Windows 2003 does not allow any more this kind of directory navigation. But, instead of Unix systems, "/" is the root of the site and NOT of the system ;-) I wonder now if you plan to either:
1. Change your platform to Windows 2003 OR 2. Simply make these changes OR 3. Have me as W2K3 tester
