What is the difference between Sage 100 ERP Version 2013 Download and Sage 100 ERP Version 4.5 Download. And then there is Version 4.5 Product Update 6 with 4.50.6 and Version 2013 with Product Update 2 (5.00.20) - how do I know which update I should be doing - and is there an order I should do them in? I am currently using version 4.50
Thank you!
