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?

Subject: Re: [WiX-users] Removing a previous Installshield installation 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). -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/> ------------------------------------------------------------------------ ------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
