This issue applies to existing customers moving to Accountants 2.0 (or any other new zone). After moving to a new zone, the Windows Desktop Client (WDC) installer will not detect the new software, and the customer will not be able to install it.
We are not deploying a new WDC version that is aware of zones to existing customers. Therefore, a WDC version of 220.127.116.1110 or prior does not understand the concept of zones and will not install the new software.
Note: A zoning-aware WDC will be available 10/21/15, at which point this issue will not exist.
