qmcl.exe not compatible with this version of Windows

[trader]

I'm trying to run qmcl.exe from a CMD window on a Windows Server 2012 machine, but get the message that this version of qmcl.exe is not compatible with the Windows version running on this computer. I tried running in compatibiity mode, but get the same message.

I searched this forum but couldn't find an answer. I'm running QM 2.4.3.4. Any suggestions?

Thanks
