eM Client is an email client that supports Gmail, Exchange, and other email providers. The application can be run as a Windows Service using FireDaemon Pro, which lets you start the application automatically at boot prior to login, start multiple instances of the application and more. This HOWTO will show you how to set it up. You can also use Fusion to manage FireDaemon and other Windows services via a web browser.


eM Client Setup Under FireDaemon Pro

Download the latest eM Client files from the official website.


Install the eM Client application. Be sure to uncheck "Run on Windows startup" on the last screen of the installer.


Run the application at least once to change any settings and add your emails.


Download and install FireDaemon Pro into the directory of your choice, typically C:\Program Files\FireDaemon.


Next start the FireDaemon GUI from the desktop shortcut. Click on the "Create a new service definition" button in the toolbar (or type Ctrl+N) and enter the information into the fields as you see below. Adjust the paths to suit your installation.



  • Executable: The path to the MailClient.exe file. The default path is C:\Program Files (x86)\eM Client\MailClient.exe
  • Working Directory: The directory containing the MailClient.exe file. The default path is C:\Program Files (x86)\eM Client
  • Parameters: None. Leave this field blank.


Now click on the Settings tab. If you DON'T want to see eM Client running, uncheck the Interact with Desktop check box & select "Hidden" from the "Show Window" dropdown. You must run eM Client as the user you installed it as. In the Logon Account field type your username (e.g. Administrator) and then enter the user's password twice in the Password and Confirm fields. You can change the Process Priority to allocate more CPU time to eM Client or specify which CPU or core eM Client will run on (in the case of multi-processor, hyperthreaded or multi-core CPUs).



Now click OK to finish setup and start eM Client!
