Error 63 run-time engine

[kataclisma77]

Hi, I'm trying to communicate with an instrument through TCP/IP using AK protocol. I've created a VI that works fine on my PC where I have installed Labview 2011.
When I create an executable from this VI to use it on a PC without Labview, it does not work and I receive the error 63.
Of course, I've have installed run-time engine and also VISA run-time, and I use the same configuration on the port (same ip address and port).
Moreover, the executable works also fine on my pc as well as the VI.

Have you got any suggestion?

Error 63 is "LabVIEW:  The network connection was refused by the server.". 

Is the target machine on the same subnet as the instrument?

No routers/firewalls between the two devices?

Net nanny/web filtering/firewall turned off on the target PC?

Instrument doesn't have to be configured to allow connections from the target machine's IP?

My guess is network configuration.  Try pinging the instrument's IP from the target machine, see if that goes through.

First thought was missing drivers/modules, but since you've got VISA and RTE installed, I think you're covered there.

Thank you very much SnowMule for your kind and fast answer.

However, I solved the problem. There was a conflict in the net configuration regarding the addresses.

Thank you again. Best regards.
