This project is for the technically astute. If you are not an expert don’t attempt. It is not my intention to diagram a step-by-step solution here; rather we shall touch upon the major considerations regarding the use of multiple MJ’s on a single machine. This project has been tested under Windows 2003 R2 x64.

As we begin, create accounts and services for each device you intend to use per instructions found elsewhere in this forum. Frank Zappa’s procedure is ideally suited for this project. Unique service names and accounts are strongly encouraged. »Running MagicJack as a Service

Outlining the issues you will encounter: magicjack.exe is compiled to run as a single instance. This limitation is overcome by renaming the executable. Next, eliminate the need for magicjackloader.exe, as this program can only be used to launch magicjack.exe and is inconsistent with the goals of this project and is a source of failure.

The following is a command line switch:
"/scf _magicJackPersonalDataRoot \"%drive%:\\%yourdataroot%\"

It is useful to execute the renamed magijack.exe; and is suited for other purposes.

Now, let us discuss conflicts; primarily I am speaking of the mounted drives enumerated via the MJ software. Using the tools provided within windows it is possible to permanently set drive letters. In other words, instead of letting windows pick the drive letter for a mounted drive, you can force a pre-determined drive letter assignment. You can also prevent drives from being mounted at all. No drives need to be mounted for this project to work successfully.

Other possible conflicts would have to do with USB audio device assignment. The tigerjet drivers support multiple instances, so this is not difficult to overcome. It may not be necessary to address this at all; it depends on the overall environment.

Impossible? I'm a bonehead, I don't beleive it!
