Sage 300 Construction and Real Estate (Sage 300 CRE) uses a different version of Pervasive than Sage 50 and Sage 300 ERP (or any other third-party software application that uses a Pervasive database structure).

Note: The Pervasive versions are not compatible. You cannot install Sage 300 CRE on the same computer as Sage 50, or Sage 300 ERP.

The issues below may occur with the installation of Sage 300 CRE and third party applications that use the Pervasive database engine:

• Corruption in Sage 300 CRE Data, the third party application data or both data sets.
• The third party application data may no longer be compatible with the Pervasive database engine that was originally installed with the third party application.

Workaround:

1. Use Terminal Services to run Sage 300 Construction and Real Estate.
2. If you need to be able to use Sage 300 CRE on the same computer as Sage 50, Sage 100 ERP, or Sage 300 ERP, use Terminal Services to run Sage 300 CRE on a terminal server and have user that need access to Sage 300 CRE log into a remote session on that terminal server.
