Hi, I am trying to install Cassini web server on XP.  It seems to install ok and opens the 
http://ultidev.com/Produ...ini/CassiniDevGuide.htm page.  However, the only options I have in the menu are
 - About Cassini Web Server for ASP.NET 2.0
 - Restart Cassini for ASP.NET 2.0 Service
The error log has the following message:
The description for Event ID ( 11001 ) in Source ( MsiInstaller ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: Product: UltiDev Cassini Web Server Explorer -- Error 1001. ; (NULL); (NULL); (NULL); (NULL); ; .
I have also downloaded the following files.
 - CassiniExplorerSetup.msi
 - CassiniServer2Setup.msi
When I try to install CassiniExplorerSetup.msi, it gives me the following error message:
The installer has encountered an unexpected error installing this package.  This may indicate a problem with this package.  The error code is 2869
There are two new errors in the log:
The description for Event ID ( 11001 ) in Source ( MsiInstaller ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details.

Running the CassiniServer2Setup.msi, I am asked if I want to Repair or Remove.  If I choose repair, I recieve the same message as above:
The installer has encountered an unexpected error installing this package.  This may indicate a problem with this package.  The error code is 2869
Again, two new errors are added to the event log:
The description for Event ID ( 11001 ) in Source ( MsiInstaller ) cannot be found.

Product: UltiDev Cassini Web Server for ASP.NET 2.0 -- The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2869. The arguments are: ErrorDialog, , 
Is there something in my configuration that is preventing the install?
Thanks in advance!
