There are two applications that are not supported in the 64 bit version off ETS: "Private Information Manager" and "Document Manager"
These applications are of limited use, especially the PIM since many web addresses are dynamic and change everytime you log-on. HTTP supported password management is "old" and is being replaced with certificate based authentication; true to the specs of the TCG. Other than these two applications the 64 bit version is fully functional like the 32 bit version. I've worked with it.
