I have installed the IA64 version of Regina 3.4 (regina34w64.exe) on an Itanium box:
HP Blade server (Intel Itanium 2)
OS: Windows Server 2003 Enterprise Edition SP2

When I call rexx.exe (or regina.exe) I get error:
Teh image file ...\rexx.exe is valid, but is for a machine type other than teh current machine.

Is there another build for this server ??
