In the process of setting up a virtual network of processors, a minor installation bug was discovered. When installing pwrrt_5.4.0-1_amd64.deb onto LUBUNTU 14.04 LTS, /pwrp/x86_linux folder and sub-folders are created, but not x86_64_linux folders and sub-folders. When distributing a project to a processor, an error occurs (paraphrased: "folder _x86_64_linux/exe is not found").
The fix is easy. Simply rename folder /pwrp/x86_linux to /pwrp/x86_64_linux.
