Claude,
I made the change, rebuilt the .app, but I still don't get the virtual directories built in IIS when I try to run WebAppBuilder.app.
>Yes, in the ServiceExist procedure in Form1 in the WebAppBuilder form, it only checks for Win2K and WinNT - NOT WinXP. So, either comment that code out or add the check for WinXP or WinNT and above. After this everything should work perfectly for XP and WebAppBuilder...
