Info:
Win7 32bit machine (tried on 2 separate machines).
Existing Cassini web server and registered pages installed.
Using Inno setup install script.
command line that is executed : msiexec.exe /passive /i UltiDev.Webserver.msi
The installation fails.
so running the installation manually: msiexec.exe /i UltiDev.Webserver.msi
We get the following error when attempting to register the Web Server App Redirector
Failed to register or unregister application due to "System.ArgumentException: An item with the same key has already been added

at UWS.Configuration.Metabase.LoadLegacyCassiniAppData(List1appPools)

Command line:
... UWS.RegApp.exe /AppID:4fd8b3f7-bc73-4583-95fe-e7b69b10a3ae

if I manually edit the CassiniMetabase.xml file to remove the web explorer application, then we install correctly.
