Step 3. Allow the Print Driver to work in the Eptura Workplace Web app

Internet Explorer

For the print driver to work in the Mail module you must open and use Eptura Workplace within Internet Explorer. If your company only has Microsoft Edge then you can change the browser settings to Internal Explorer mode.


First, we recommend you contact your IT team to find out if they manage the browser settings.

  • If they manage the browser settings then you will need to request them to change the settings. 
  • If they don't manage the browser settings then you can follow the steps in this article called How to use Internet Explorer mode in the Microsoft Edge browser for Windows 11.
  • Follow the below steps to Enable pop-ups in Microsoft Edge:
    1. In Edge, click the More Actions ••• icon, found at the top-right of your browser.
    2. From the menu, click Settings.
    3. From the Settings menu, click Cookies and site permissions.
    4. Under the All permissions area, click Pop-ups and redirects.
    5. Toggle the Blocked (recommended) to OFF.



When you have the Eptura Workplace site in Internet Explorer or use Microsoft Edge in Internet Explorer mode, you can complete the following:

1. Navigate to Mail > Receiving Queue.

2. Click on a package.


Next, you will get a popup saying SeagullWebClientRuntime is not installed or is inaccessible.


3. Click the OK button.

4. Locate the popup at the bottom of the screen.


5. Click the drop-down arrow next to Allow and choose Allow for all websites.

The page will refresh, next try to print a label again. If everything is installed correctly it will print.
