We are planning to setup a Virtual Machine with the Pinnacle software
for use by our organization.  We want to maintain  the same set of versions (CDISC CT, UNII, NDF-RT, FDA engine)
for all the reports in a study so we are planning on not having the virtual machine
connected to the internet so the definitions are not updated during a study.  

If we want to update the versions after we complete a study how can we do that?
Does the software check for updates each time it starts or is there some algorithm 
that dictates when the update is performed?  Is there a way we can (other than not
allowing the software to access the internet) control / disable when the software updates?
