Can you use an RB-530 box with E-Run?

Sigh.  This bit of misunderstanding seems to never go away.  Let me 
try once again to set this straight.  Doing a "Subject Station" 
installation of EP does *not* free up a dongle to continue 
developing, for the simple reason that doing a full installation of 
EP does not *tie up* a dongle in the first place.  You may do a full 
installation of EP on as many machines as you like within your 
lab.  Whichever of those machines has the hardware key ("dongle") at 
that moment can be used as the development machine, any others work 
in effect as subject and data stations.  Let me repeat 
that:  E-Studio is the only application of the E-Prime suite that 
requires the hardware key in order to run; all the others (E-Run, 
E-DataAid, E-Merge, etc.) will run without the hardware key.  Having 
E-Studio installed on a subject station does not interfere at all 
with its use as a subject station, to the contrary it only means that 
it could be pressed into service as a development station at any moment.

Thus, doing a Subject Station installation provides no benefit 
whatsoever, and from what I see on the message boards actually 
introduces problems that could be avoided with a full 
installation.  I see no reason for ever doing a Subject Station 
installation -- if you simply do a full installation on every machine 
in sight, then you can use them all as subject and data stations, 
with the flexibility that at any moment any of them can be pressed 
into service as a development station merely by plugging in the hardware key.

We have use EP around here for over decade and have installed it on 
over a hundred machines, we have *never* done a Subject Station 
installation and that has never caused a problem for us.
