sage Payroll v7.2 - issue

SUGGESTED

We have a client who we activated and installed the Payroll v7.2 for them today. One lady uses Payroll, the other lady does not. 

They are on Sage 300 ERP 2012 with the latest service pack.

We installed the Payroll v7.2 on just one workstation as she is the only person using Payroll, when the other lady tries to do her Bank Rec (she never uses Payroll) she gets the error message below:

Error: Program file problem: Bank Reconciliation Posting. Initialization file for CP must have a (Bank) section to process transactions in Bank Services. 

We installed Payroll v7.2 and she does not receive the error.

Does this mean Payroll v7.2 has to be installed on all workstations even though they do not use Payroll???
