Archicad 17 hang when a user opens 2 archicads at the same time

Question

Hello I am a system administrator in an office of architecture.
I encountered the following problem: The architects working with archicad 17 on two 02 workstations with windows 7 pro are giving the following problem:
when you open the 2 archicad windows the RAM reaches the limits and closes the both applications. This is only happening with these 2 workstations.
I do have more 12 workstation with win pro 7 and 8.1 pro and the archicad works ok.
I really could use some help. Thanks in advance.
Cheers.
Info on the workstation:
OS: Win 7 PRO
CPU : intel 4930K
RAM: 16GB
GPU: Nvidia Geforce 770 GTX
