Known Issues for Web Forms Applications

If you launch a PowerBuilder 12.5 Web Form application in the Windows 7 operating system, this 404.2 error is displayed: The page you are requesting cannot be served because of the ISAPI and CGI restriction list setting on the Web Server.

Workaround:

1. In Windows 7, open the IIS Manager and locate the IIS component, ISAPI and CGI Restrictions, under the current server.
2. Double-click the component, right-click ASP.NET v4.0.30319, and choose Allow.
3. Restart the IIS Server and the Web Form application.

If you log in as a standard user on Windows Vista or Windows 7, you cannot debug Web Forms applications or .NET Web Service components, because the debugging process cannot attach to the ASP.NET work process. The User Account Control (UAC) dialog box that enables you to elevate your privileges appears when you attempt to deploy an application or component as a standard user, but it does not appear when you attempt to debug the application or component.

Workaround: Choose Run As Administrator to launch the PowerBuilder Classic IDE and debug the application or component.
