FATAL ERROR DURING INITIALIZATION MAIL LOGGING, Tearing down process
WARNING VismaBusinessExchangeSynchronizerMailLogService..ctor: Exception thrown: System.MissingMethodException message: Method not found: 'Visma.Licensing.Client.LicenseResponse Visma.Business.MailLog.Connection.LicenseManager.CheckLicense(Int32, System.String, System.String)'. trace:

How to fix

Most likely one or more dll files from the previous version have not been replaced by the new version. 

What to do in this case:

  1. Uninstall the Maillogger on the server (the configuration will not be removed)
  2. Make sure the maillogger folder in program files is removed.
  3. Download the correct setup from Vismaplaza.com
  4. Make sure the file is ot blocked (right click > properties > unblock (if possible)
  5. Run the installer

After this try and start the Maillogger again.
