When we moved over to MSI we had to deal with existing InstallShield installs. I got round the problem by looking in the registry for the key InstallShield writes under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall using a RegistrySearch. I then used the set property as the condition for a custom error telling the user to uninstall the existing version. This might seem crude, but it does the job and each customer only has to do it once.
