Windows restart required after server installation changes

Windows might show the error Please wait while the current program is finished uninstalling or being changed after you change an installation of Meridian Enterprise on a server with the Repair or Change commands in the Programs and Features applet in Windows Control Panel. This is because the Meridian installation package starts the 32-bit version of Meridian Application Integration ( AMHookTrayU.exe) and 64-bit (AMHookTray.exe) after installation has completed and Windows Control Panel is waiting for them to terminate, which they are not designed to do.

This only occurs:

  • With versions prior to 2016
  • If the Meridian installation package is started from Windows Control Panel, not from Windows Explorer.
  • If the Meridian Application Integration processes were started by a previous running of the installation package from Windows Control Panel and not during Windows startup. That is, you are running the installation package multiple times in the same Windows session.

This does not occur in recent versions of Meridian installed on client PCs.

You can avoid restarting Windows by manually stopping the Meridian Application Integration processes:

  • Right-click the Meridian Application Integration icons in the system tray and then click Close in the shortcut menu that appears. If the error persists, open Windows Task Manager and look for other Meridian processes that may have been started by the installation package and stop them also.
