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

[Marc Chantelois]

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.
