SuperOffice Onsite is being phased out, and no further compatibility testing will be performed in the future. | Server | Client | Version | ODBC driver | | -------------------- | ----------------- | ------------------------ | ----------------------------------------------- | | Oracle 18c | Oracle 18c Client | 18.3.0.0.0 | See Oracle 18c compatibility | | Oracle 12c | Oracle 12c Client | 12.1.0.1.0 | Oracle in OraClient 12home 12.01.00.01 | | Oracle 11g Release 2 | Oracle 11g Client | 11.2.0.1.0 | Oracle in Orahome11 v. 11.2.0.3.0 or 11.2.0.1.0 | | Oracle 11g Release 1 | Oracle 11g Client | 11.1.0.7.0 or 11.1.0.6.0 | Oracle in Orahome11 v. 11.1.0.7.0 or 11.1.0.6.0 | For Oracle 12c and 11g, use driver file *SQORA32.DLL*. ## Oracle 18c compatibility SuperOffice does not run on Oracle 18 ODBC drivers. You may run Oracle 18 on the database server, but you need an older Oracle 12c ODBC driver on the SuperOffice client/server. Our existing customers can upgrade their database servers to Oracle 18c, and as long as they do not upgrade the database drivers on the machines running SuperOffice it will continue to work. ## Related topics - [Install SuperOffice 8 Windows client](/en/onsite/install/win-client/win8-client.md) - [Install SuperOffice 9 or 10 Windows client](/en/onsite/install/win-client/index.md) - [Tested browser versions](/en/onsite/compatibility/browser.md) - [Tested Microsoft Office versions](/en/onsite/compatibility/ms-office.md) - [Databases supported by SuperOffice CRM](/en/onsite/compatibility/database.md) - [Tested server operating systems](/en/onsite/compatibility/server-os.md)
