I know that the binaries are different, but the registry key that WPKG checks is the same for all WOW64 implementations.

The variable named x64 is used to indicate if we are running in an 64-bit environment, but it does not indicate, if we are running
on AMD64 or IA64.

Sure it would be better to have feedback from one who is actually using such a system, but the hardware is expensive and the Itanium
processor is only used for server systems now, since workstations were seldom ordered by customers.

Thanks for implementing the enhancement, so WPKG can be used by IA64 users in the same way like the rest of us.
