We have several clients that are running Sage 100 2017 when Payroll was still part of the normal install process.  It is my understanding that these people have to upgrade to the new 2.19 (soon to be be 2.20) Payroll which is a separate install.  To this point, I have been unsuccessful in finding a document that describes and walks through the update/upgrade process.  Any assistance that anyone can offer is greatly appreciated!!!
