Some of the old software before 2010 may not be able to install/run normally on x64 or Windows 10 systems. Be aware of it before purchasing it.




- Workgroup Edition
This edition is only allowed 5 CALs maximum, it is not possible to add more CALs. If more CALs are needed, an upgrade to Professional or Enterprise should be done. Also all the server roles are installed on 1 machine and cannot be separated. You can only create 1 organization in this version and the use of external connectors is not allowed. This version is ideal for small organizations that can use it with the SQL Server Workgroup Edition and on a Windows Small Business Server.
- Professional Edition
The Professional Edition has the same functionality as the Workgroup Edition except there is no limit on the CALs. If the installation profile calls for supporting either multiple organizations or servers, the Enterprise Edition is required.
- Enterprise Edition
Has the same functionality as the Professional Edition but without limits. This version is to be used when multiple divisions should be accessing CRM from one platform.
