Which per-user one ? There could be multiple per-user installations on a machine. You'd have to be an admin to detect the per-user installation of another user. The other users might not be too happy if someone came along and removed their installation if it had some user-specific configuration/customisations that weren't carried over to the new per-machine installation. It sounds like the kind of thing that ought to be sorted out manually, rather than automatically.
That said, if your environment means this kind of thing would be ok, then you can enumerate per-user installations with the MSI API call MsiEnumProductsEx() (or DTF equivalent, if there is one) and passing the appropriate context arguments. This would only detect that such products exist. MsiConfigureProductEx could then be used to remove them but I wouldn't do this in an installer... maybe as part of a chainer. -----Original Message----- From: Martin Kulov [mailto:mar...@kulov.net] Sent: 13 October 2011 10:47 To: wix-users Subject: Re: [WiX-users] major upgrade from per-client to per-machine install Hi everyone, Is there a way to detect per-user installation and so that per-machine install is prevented unless the per-user one is uninstalled first?
