Uninstall PI AF server

You must have administrator privileges on a computer to uninstall PI AF server.

This procedure describes how to uninstall PI AF server using the PI Server Maintenance wizard.

1. Make sure other users are logged off.

2. Open the Windows Control Panel and select Programs and Features.

3. Double-click PI Server <release> Installer.

   The Maintenance wizard for PI Server opens.

4. Select Modify and click Next.

5. Select the Server Roles tab if it is not already selected.

6. Clear AF Server and click Next.

   If you are uninstalling PI AF server but not also uninstalling PI Notifications Service or PI Analysis Service, a window asks you to confirm that this configuration is intentional.

7. Click Uninstall or Modify.

   The Modify option appears if there are other PI Server components that you did not choose to uninstall.

   The uninstall process begins.

The uninstall process does not remove the PI AF SQL Server database and any database backup files. If the same version or a more recent version of PI AF server is later reinstalled, any existing PI AF SQL Server database will be used and upgraded as necessary.

During an uninstall, the files listed below are not removed automatically. You can remove them manually. Unless otherwise noted, these files appear in the %PIHOME64%\AF directory.

• AFService.exe.config

• AFService.pfx

• AFSDK.config

• AFTRACE*.config

• Log files (*.log)

• Log files (*.log) in the %PIHOME64%\DAT or %PIHOME%\DAT directories.

Several products share the %PIHOME64% or %PIHOME% directories as well as the PIPC.INI, PI.ICO, and PI16.ICO files. After uninstalling PI AF server, you can remove any of those files or directories if they are no longer needed.
