yes, sure! Ready Pro can be easily configured in order to work properly in a network.
You just have to create (or to move if you have already created it) your Ready Pro archive in a shared directory on your server, where all the 3 users have permissions for reading and writing on it.
Then simply install Ready Pro on the three workstations and open the existing shared archieve.
The 3 users will be able to work at the same time on it.
Thank you for trying Ready Pro, your feedback is really precious for us!
I remain at your disposal for any further question.
