 subject: KFW: BUG: WIX: Improve Usability of multiple architecture MSI installations, remove non-unique GUID component identifiers, and include Beta ID in the package name
 component: windows
 tags: pullup
 target_version: 1.6.3

 The WiX installation package suffered from several problems:

  * The Beta ID was not being included in the package name.
    Fixed this by swapping the priority of "Release" and "Beta".
    "Beta" is an official release that has a beta value.
    A non-release has a datestamp as part of the package name.

  * There were duplicate GUID values being used for registry components.
    This would prevent proper removal of the components on uninstall.

  * 64-bit Installers were being constructed with the 32-bit installer
    schema.  This prevented side-by-side installation of the 64-bit and
    32-bit versions.  This also permitted 64-bit installers to be
    installed on 32-bit systems.

  * The 64-bit and 32-bit installers had the same package name.
    64-bit and 32-bit are now identified in the package name.

  * 64-bit files were being installed to the WOW64 environment.
