Hi,
That should be no problem at all. Any machine with or without NI software can use an FTP client to transfer files to and from an RT target such as CompactRIO.
You should be able to build the executable on the development machine, transfer it via USB drive to another machine and then use FTP software to transfer the file from there. You'll just need the IP address of the target and login information.
For more information on FTP transfer with or without MAX to RT targets, see the following KB article:
