Constraints

You cannot mix 32- and 64-bit ACE ODBC drivers on the same machine (64-bit ACE available starting with Microsoft Office 2010).

You cannot mix 32- and 64-bit PC Files Servers on the same machine.

The “bitness” of the ACE driver must match the “bitness” of PC Files Server. The installer enforces this but care should be taken if the ACE driver is ever replaced.

If SAS on Windows matches the “bitness” of the installed ACE driver, then PC files can be accessed directly using the EXCEL and ACCESS engines.

If SAS on Windows does not match the “bitness” of the installed ACE driver, then PC Files Server must be used to bridge the “bitness” gap. The Autostart feature simplifies this when running SAS on Windows.

The server can run in server mode or service mode. However, only one instance of the server can be running on a single PC at any given time.

Service names and port numbers must be unique on a given PC.

To modify the settings to follow the constraints:

Each time that you stop or restart the server, all users' sessions are closed. Closing these sessions might result in loss of data.

Although you can change server configuration only in server mode, the updated values also apply when running in service mode.
