Thanks Richard, I kind of guessed that was the case.

I have two further questions....
1) Would it be possible to set ALLUSERS and then detect the previous 
products and if found, give a warning and exit the installer.  If a 
previous product isn't found then clear all users and continue with the 
installation as normal?  This would mean the user is forced to manually 
remove the previous product first before the newer one is installed.

2) Got any recommendations of a good bootstrapper?

Thanks

Chris

You can't upgrade away a per-machine install with a per-user install and 
vice-versa.  The best way to handle this is to set ALLUSERS according to 
what was installed previously and not let them change it during the 
upgrade.  Another way of dealing with it is to cope with it in a 
bootstrapper and force them to remove the old product before installing 
the new one (which means its not an in-place upgrade at that point).
