Hi Expert,

I know NAV 2009 SP1 can run 64bit. If i install at 64bit operation, it is actual running 64bit or 32 bit on x64. May i know nav 2009 has another 64bit version?

When i read sys. requirement it said.

Operation System
Microsoft Windows XP Professional SP3 or later (X86 or running 32 bit on X64)
Microsoft Windows Server 2003 SP2 or later (X86 or running 32 bit on X64)
Microsoft Windows Server 2003 R2 SP2 or later (X86 or running 32 bit on X64)
Microsoft Windows Vista (Business, Enterprise, or Ultimate) SP1 or later (X86 or running 32 bit on X64)
Microsoft Windows Server 2008 (X86 or running 32 bit on X64)

When i install at 64bit operation system, which advantages can i get? Any other doc. for that?

Best Regards,
Yukon

Well, when it says “NAV 2009 SP1 runs on 64bit OS” this only means you could start NAV without crashing [6]
Yet, NAV cannot take advantage of 64bit memory addressing, thus, technically it’s the same as a 32bit thing.
Or in other terms: there is only one NAV 2009 SP1 version - this is a 32bit thing which runs on 64bit OS in “Windows on Windows” mode.
