You might want to have a read over at http://stackoverflow.com/questions/14814014/msi-multi-instance-installation-with-patches. Multi-Instance installs are tricky enough to get right, adding the patching on top of it can become real confusing rather quickly. Other than that, there isn't much we could do without the command line / logs from when you are trying to apply the second patch (the failing one).

(wix-users@lists.sourceforge.net) Subject: [WiX-users] General question about patching multi-instance MSI installs I am currently working on implementing a multiple instance MSI base installation using WIX and am trying to validate that patching will work correctly before I go any further. I have been able to create a patch that updates all instances exactly as I would suspect, but when I try to install a second patch, I get a 1642 error that the product to be updated is not installed. If I uninstall the existing patch the new patch will install just fine so I am thinking that the issue might be version related since the patches are all cumulative. I checked the installation logs and they do not tell me anything about what the issue might be and I am hoping someone else has hit a similar situation and can tell me what settings in the PCP file I need to check for this to work.
