Hi ,
you have to use the same VEPRO version on both your Master and your slave machine(s).
This will narrow down the possibilities you have with an older machine in combination with current models.
Not long ago I actually still used my G5 in my setup , so here are the specs of that setup :
Setup until Summer 2011
PPC G5 / OS X 10.4 / VEPRO 4 Build_4.1.8008
Macpro / OS X 10.6.8 / VEPRO 4 Build_4.1.8008
( Actually VSL released VEPRO4 until version 4.1.11889 in December 2012 ,
however I used the above listed version because it worked flawless on my setup, and
I didn't dare to change a running horse . )
After that , until recently:
PPC G5 / OS X 10.5.8 / VEPRO 5 Build_5.1.11548 ( the last version of VEP5 that worked on PPC )
Macpro / OS X 10.6.8 / VEPRO 5 Build_5.1.11548
( The corresponding eLicenser version compatible with PPC was version 6.3.6.1098 , I think. Not quite sure here. )
These setups worked very well.
However , switching from VEP4 to VEP5 required to rebuild some mframes from scratch , because some of them
didn't worked properly after a simple conversion ( ... that is opening a VEP4 mframe with VEP5 ) .
In short : you cannot use the current available version of VEPRO5 on your PPC.
Instead you have to use a former version of VEP on both your PPC and your current machine.
While VEP4 is still available in the download section , I can not see the "VEP5 version Build_5.1.11548" which worked
on PPC with OS X 10.5.8 .
Hope this helps ,
best wishes
