If you installed multiple versions of the .NET Framework on the
target Web server, you should make sure that IIS uses a supported version for PowerBuilder
.NET applications.

1. Select Start > Run from the Windows Start menu.
2. Type InetMgr in the Run dialog box list.
3. In the left pane of the IIS Manager, expand the local computer node and its Web Sites sub-node.
4. One of the following:
   • For all new Web sites, right-click the Default Web Site node and select
     Properties.
   • For already deployed projects, expand the Web site node and right-click the .NET application
     that you deployed from PowerBuilder.
5. Specify the ASP.NET or .NET Framework version.
   • On Windows XP, open the ASP.NET tab and choose the ASP.NET version:
     • For PowerBuilder 12.0 and earlier: 2.0.50727
     • For PowerBuilder 12.6:
       4.0.30319
   • On Windows 7, Windows Vista, and Windows 2008, set the .NET
     Framework version used by your NVO Web service deployment:
     1. In the IIS Manager, open the Application Pools node
        underneath the machine node.
     2. Right-click the PBDotNet4AppPool filter and choose
        Advanced Settings.
     3. Set the .NET Framework Version to
        4.0.
