Quicken, any feature level, is not designed for use by multiple users sharing the same data file. 
In
 short: one computer, one Windows User Account, one installation of 
Quicken on that computer, one (or more as needed) Quicken data file(s) on the computer's internal hard drive or SSD. 
Additional people can use this environment when 
needed, one person at a time but they all have the same full, unrestricted 
access to all functions of Quicken.If you have a need for two
 or more people accessing your bookkeeping data at the same time, 
performing order entry or other tasks (shipping, invoicing, etc.) then, 
IMHO, Quicken is not suitable for you. I would recommend you start 
looking for a full-featured multi-user capable accounting software 
package, one that is customizable to suit your business needs.
