Thanks for the suggestions. As part of my troubleshooting, I performed the suggestions prior to my posting. There is the UltiDev menu option under Start->Programs but it is empty. As for Add/Remove programs, it only showed the option for UltiDev Cassini for Web Developers 2005.
I had checked the windows event viewer and this is what I found:
Product: UltiDev Cassini Web Server for ASP.NET 2.0 -- Error 1001. Service Install():
System.IO.FileNotFoundException: Could not load file or assembly 'Interop.IWshRuntimeLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cc16caed94880aaa' or one of its dependencies. The system cannot find the file specified.
File name: 'Interop.IWshRuntimeLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cc16caed94880aaa'
at CassiniService.ProjectInstaller.CreateProgramIcon(String targetPath, String shortcutName, String iconLocation, String description)
at CassiniService.ProjectInstaller.CreateShortcuts()
at CassiniService.ProjectInstaller.Install(IDictionary stateSaver)
After some experimenting, I went into Program Files and deleted the entire UtilDev directory. Then I attempted another install of Cassini and all was successful. I should have attempted the delete of the directory prior to posting but it did not occur to me.
