View Full Version : Possible to chain 64-bit MSI to 32-bit MSI?

I tried chaining a 64-bit MSI to a 32-bit MSI and only running the chained MSI if the 32-bit parent was installed on a 64-bit compatible machine. This seemed to work great, until I noticed that the chained MSI was installed to the 32-bit Program Files directory. When I uninstalled the chained program and ran it again manually, it installed to the 64-bit Program Files directory. So it seems like to run a 64-bit chained MSI, it has to be chained to a 64-bit parent program. Can someone confirm this?

Heath Stewart blogged about this limitation in Windows Installer a while back, in his article Installation sequence restrictions for multi-package transactions (http://blogs.msdn.com/b/heaths/archive/2009/07/03/installation-sequence-restrictions-for-multi-package-transactions.aspx).
