## Collection of notes about WiX usage

## for x64 add InstallerVersion="200" Platforms="x64"
## see http://blogs.msdn.com/astebner/archive/2007/08/09/4317654.aspx
## Or something like
##<Condition Message='This application is for x64 Windows.'>
##  VersionNT64
##</Condition>
## Actually seem to need both, and it is 'Platform' in WiX 3.0

## ALLUSERS = 1 for per-machine, blank for default.
