Probably not. The WiX custom actions are currently 32-bit because we 
were able to work on 64-bit portions of the file system by disabling 
file-system redirection when necessary. It's available in wcautil.lib; 
see the source code in src/ca/wcautil/wcawow64.cpp.

That will be changing soon. The file-system redirection API doesn't 
solve problems with the registry, so we're adding support for 64-bit 
custom action builds. That will probably appear in the next couple of weeks.
