[wix-users] installing 64 bit files within a 32 bit MSI [P]

[David Watson]

You can't install a 64 bit msi on a 32 bit OS so your MSI would need to be 32 bit.
You can't write to 64 bit locations (registry, program files etc) from a 32 bit msi on a 64 bit OS.

The correct way is to have two MSIs.
So if you don’t care about logo compliancy and suppress ICE you can fudge things.
But why fight the OS and make work for yourself when you are already doing the right thing?

Yes this is the way I currently create my MSI's (if there are bitness differences in the binaries)

I compile 1 as x86 and then compile the same project as x64 and have a bundle that runs the proper MSI depending on bitness of OS

However our PM would like us to go from 2 MSI's down to 1 and use Win64 in the 32 bit MSI to install the 64 bit binaries (with conditions of course)

Thanks,

Steve

What about the registry ?  I had to create a custom action for a 32bit msi to write in to the 64bit registry.  (Unable to generate dump file of the install app if i don't write in the 64bit registry for dump)

For me, the same wix files are making the x86 and x64 msi.  I have 1 vstudio project for each solution.  There is only a change in the project files (-arch x64).  The rest of the variation are include in the definition files with some ´if(sys.buildarch = x64)´.  It is still 2 msi but i always wrap them in a single bootstrapper.
